Personal wealth is created in one of two ways. On the positive side, it  arises as a result of innovation, hard work, brilliant insights, or even  luck. Entrepreneurs create enormous wealth when they have a better idea  (Henry Ford’s assembly line), discover and develop new products  (Microsoft Windows or Google’s search engine), see a new business model  (Sam Walton), or are simply at the right place at the right time. Often,  it is a combination of innovation and timing, something economists call  network externalities. 
A second and negative route to personal wealth is through political  connections, lobbying to obtain benefits from the state, violence to  remove competitors, or outright theft of public resources. Those who  earn their fortunes  the first way create jobs, raise productivity, and  contribute to economic welfare. Those who use the second route are “rent  seekers” who subtract from growth and welfare for their own benefit. 
Bill Gates, Sam Walton,  and Sergei Brin  represent wealth earned  through entrepreneurship. Their Microsoft, Walmart, and Google made them  not only among the richest persons in the world. They have created new  technologies, hundreds of thousands of jobs, new business models, and  have revolutionized they way we gather and process information. Carlos  Slim, the world’s wealthiest man, made his fortune by monopolizing  Mexico’s telecommunications market (presumably with help from government  regulators).  Poor Mexicans have been denied the wide range of choice  of telephone services that others have and  pay for his wealth in the  form of the highest telephone rates on the continent.  
The most egregious rent seeking occurs in autocratic and dictatorial  regimes in which wealth accumulation is not constrained by an  electorate, corporate transparency, or a free press. Such authoritarian  regimes breed kleptocrats –those who accumulate  wealth for themselves  through their official positions. Oligarchs are those who use their  access to those in power to accumulate wealth. Both kleptocrats and  oligarchs transfer assets from society or from others to themselves;  they do not create new products or additional jobs. They reduce economic  welfare by crowding out real entrepreneurs, who refrain from economic  activity knowing the fruits of their labor will be stolen. Kleptocracy  and oligarchy are determined by the quality of society’s institutions  and rule of law. The better the institutions, the more limited  kleptocracy and oligarchy.
I present here some  data on the world’s kleptocrats, oligarchs, and top  entrepreneurs.  The wealth of  kleptocrats cannot be measured with any  degree of precision because, as heads of state or government officials,  they wish to conceal it. However, the figures capture rough orders of  magnitude. Oligarchs, not being government heads or officials, are less  prone to conceal their wealth. They may even feel a sense of pride when  they see their names listed in Forbes.
I begin with a ranking of kleptocrat heads of state  by absolute wealth.  (I convert the wealth of past kleptocrats into current dollars). Four  of the top six rule (or ruled) countries with rich natural resources  (Putin, Nazarbaev, Aliev, Mobutu), such as energy or diamonds. The real  “oil curse” is therefore the tendency of the rulers of mineral-rich  countries to steal the national wealth. Other kleptocrats  controlled   poor countries lacking access to rich natural resources. The recently  deposed Mubarak (whose personal wealth is listed at the maximum  estimate) is in the middle range of notable kleptocrats. Of the eleven  countries represented, four (Philippines, Indonesia, Nicaragua, and  Peru) have subsequently democratized, although Nicaragua’s democracy may  be shaky. Democracy strikes at the root causes of kleptocracy by making  the rulers accountable to an electorate and investigative journalists.
| Ruler(ranked top to bottom) | Year |  |  | Wealth (bl. 2010 $) | 
| Putin (Russia) | 2011 |  |  | 40 | 
| Suharto (Indonesia) | 1998 |  |  | 25 | 
| Nazarbaev Kazakhstan) | 2011 |  |  | 20 | 
| Marcos (Philippines) | 1986 |  |  | 7.5 | 
| Aliev (Azerbaijan) | 2011 |  |  | 10 | 
| Mobutu (Congo, Zaire) | 1997 |  |  | 5 | 
| Mubarak (Egypt) | 2011 |  |  | 5 | 
| Abacha (Nigeria) | 1998 |  |  | 3.5 | 
| Milosevich (Serbia) | 2000 |  |  | 1 | 
| Duvalier (Haiti) | 1986 |  |  | 0.55 | 
| Fujimori (Peru) | 2000 |  |  | 0.6 | 
| Alemain (Nicaragua) | 2002 |  |  | 0.1 | 
| Estrada    (Philippines) | 2001 |  |  | 0.08 | 
Heads of state who steal from less populous countries (Serbia, Haiti,  and Nicaragua) accumulate less wealth ceteris paribus than those in  populous economies (Russia, Indonesia and Nigeria). The grazing ground  for kleptocrats is less spacious in poor countries than in  rich  countries. The percentage of the kleptocrat’s wealth  to GDP is a  measure of the kleptocrat-head-of-state’s s burden on society. This  table shows that Mobutu, at the end of his reign in Congo, had  accumulated wealth equal to more than forty percent of the nation’s  meager output. Duvalier had accumulated an estimated ten percent – a  figure comparable to the Central Asian oil magnates of Kazakhstan and  Azerbaijan. Marcos and Suharto  are in the three to four  percent range,  whereas Putin and Milosevic are in the one to two percent range. 
| Ranked top to bottom | Year |  |  | Percent of GDP | 
| Mobutu (Congo, Zaire) | 1997 |  |  | 0.4202 | 
| Aliev (Azerbaijan) | 2011 |  |  | 0.1111 | 
| Nazarbaev (Kazakhstan) | 2011 |  |  | 0.1036 | 
| Duvalier (Haiti) | 1986 |  |  | 0.1000 | 
| Marcos (Philippines) | 1986 |  |  | 0.0429 | 
| Suharto (Indonesia) | 1998 |  |  | 0.0331 | 
| Putin (Russia) | 2011 |  |  | 0.0180 | 
| Milosevich (Serbia) | 2000 |  |  | 0.0165 | 
| Abacha (Nigeria) | 1998 |  |  | 0.0127 | 
| Mubarak (Egypt) | 2011 |  |  | 0.0100 | 
| Alemain (Nicaragua) | 2002 |  |  | 0.0073 | 
| Fujimori (Peru) | 2000 |  |  | 0.0029 | 
| Estrada (Philippines) | 2001 |  |  | 0.0003 | 
It should be noted that these figures show the economic burden imposed  only by the head of state. Heads of state have their courts, which share  in the plunder of resources. The court’s assets are not calculable, but  we imagine that, if they could be included as well, the kleptocratic  burden would be multiplied many times over. 
The next table shows the cumulated wealth of the ten wealthiest persons  in industrialized democracies (the United States, the European Union,  and South Korea), in two former Soviet states (Russia and Ukraine),  Mexico and in China. These figures omit the wealth of the head of state.  
The table shows that the top ten have more wealth in the large and  wealthy United States and European Union (between 170 and 270 billion).  Relatively poor Mexico and Russia both have nearly  one hundred billion.  (There are as many billionaires listed for “poor” Russia as for the  “rich” United States – a remarkable testimony to rent seeking in Putin’s  Russia.) The top ten in South Korea and Ukraine have the same amount of  wealth even though South Korea is five times richer. China lies between  Mexico and Ukraine although it has the world’s second largest economy. 
| Ranked top to bottom |  |  | Wealth of Top 10 (bln $) | 
| US |  |  | 264.8 | 
| EU (without UK) |  |  | 171.5 | 
| Russia |  |  | 97.0 | 
| Mexico |  |  | 90.3 | 
| China |  |  | 42.3 | 
| South Korea |  |  | 21.4 | 
| Ukraine |  |  | 17.7 | 
The US top 10 list is comprised largely of entrepreneurs whose ideas and  business methods changed whole industries (Gates, Buffet, Walton, and  Brin). The Russian top 10 list is made up of Kremlin-favored oligarchs  who were awarded extremely valuable assets that had previously belonged  to the state.  The South Korean list is populated by industrialists who  formed conglomerate businesses that compete in world markets, while the  Ukrainian list is made up of those who received valuable state assets  during privatization. China’s list is of industrialist owners of  successful Chinese companies (most partially owned with the state), who  could not have been successful without the support of the Chinese state.
The next table  shows the wealth of the top ten as a percent of GDP. In  those countries (US, EU, South Korea) where the top wealth holders play  primarily entrepreneurial roles, their share is  between one and two  percent. Viewed in the light of their contribution to the economy, their  wealth reward seems rather modest.  In Ukraine and Russia, the share of  GDP of the top ten is between four and six percent – a rather  substantial return to those making a negative or questionable  contributions to output and welfare. The high Mexican share is due to  the “Carlos Slim Effect.” He alone accounts for most of the high Mexican  figure. 
| Top 10 Persons |  |  | Wealth of top 10 as percent of GDP | 
| Ukraine |  |  | 0.0586 | 
| Mexico |  |  | 0.0583 | 
| Russia |  |  | 0.0437 | 
| US |  |  | 0.0184 | 
| South Korea |  |  | 0.0147 | 
| EU (without UK) |  |  | 0.0113 | 
| China |  |  | 0.0042 | 
China is an outlier. The wealth of its richest persons is small relative  to the size of the Chinese economy. What this suggests is that there  are forces at play, other than the usual constraints imposed by  democracy and a free press, that have limited rapacious rent seeking on  the part of  connected Chinese businessmen . At this juncture, we do not  know enough about the internal workings of large Chinese businesses to  define the entrepreneurial roles played by their chief executives.   These constraints on rent seeking in China may be one of the many (still  unexplored) reasons for China’s rapid growth.
The basic message of this analysis is that, in countries with good  institutions, generous wealth accumulation is a reward for positive  contributions to the economy. These are rewards for innovation,  radically new ideas, persistence, and risk taking. In societies with  good institutions, the rewards are relatively modest as a percent of  total economic activity. These rewards are constrained by competition,  social morays, and the rule of law. In countries with poor institution,  wealth is accumulated either by the head of state or by oligarch cronies  by transferring assets from others or from society itself. Such  transfers not only do not increase national wealth; they reduce it  insofar as real entrepreneurs cannot prosper in such an environment. 
We are often  reminded of the greed of those at the top. Little  attention is devoted to the contributions of those entrepreneurs whose  ideas and methods have contributed to economic growth. Walmart,  Microsoft and Google currently employ 2.1 million, 93,000, and 22,000  respectively. The indirect employment they create through suppliers,  vendors and other stakeholders is a multiple of these figures. Their  annual payrolls equal a large fraction of the accumulated wealth of  their founders. 
Warnings about the growing concentration of wealth at the very top must  be considered in proportion to the size of economic activity, whose  increase is in fact positively affected by those at the top.  Today, the  top ten account for less than two percent of GDP in the United States.  At the turn of the twentieth century, the top ten accounted for more  than five percent!  In a ranking of the 100  top wealth holders from the  founding of the United States to the present (as a percent of GDP),  only five living persons are listed, and Gates and Buffet are ranked  only numbers 31 and 39 respectively.
Data sources: This data is drawn from Forbes rankings of the world’s  richest people, from estimates of Transparency International, and  independent estimates of the wealth of Vladimir Putin and informal   estimates of the wealth of Nazarbaev of Kazakhstan and the Aliev family  of Azerbaijan. The wealth of  other kleptocrats is given as of the date  of their removal from power converted into 2010 US dollars. The top five  Ukrainian oligarchs are taken from  http://ukrainianguide.com/5-wealthiest-ukrainian-oligarchs/2/ Only five  Ukrainian oligarchs made the billionaire list; so I assume there are  five more slightly below one billion. Mubarak’s wealth is taken from an  ABC News report of February 11, 2011 citing U.S. intelligence sources.  These sources dismiss the high figures cited in the press and place  Mubarak’s wealth between $1 and $5 billion. I take the upper figure to  avoid underestimation. The wealthiest 100 Americans throughout history  is taken from  http://www.getrichslowly.org/blog/2006/07/29/the-wealthy-100-a-ranking-of-the-richest-americans-past-and-present/
