Occupy protesters have been mischaracterized by many people as being opposed to “capitalism.” Based on my conversations and observations, I have not encountered protesters who oppose “capitalism.” Rather, they oppose what has been described as “crony capitalism.” Compare the  follow definitions, from Wikipedia:

Capitalism is an economic system that became dominant in the Western world following the demise of feudalism. There is no consensus on the precise definition nor on how the term should be used as a historical category. There is general agreement that elements of capitalism include private ownership of the means of production, creation of goods or services for profit, competitive markets, and wage labor. The designation is applied to a variety of historical cases, varying in time, geography,

politics and culture.

In the above definition, you won’t see, as an element of capitalism, that players are allowed to rig the system.  Compare to Crony capitalism:

Crony capitalism is a term describing a capitalist economy in which success in business depends on close relationships between business people and government officials. It may be exhibited by favoritism in the distribution of legal permits, government grants, special tax breaks, and so forth. Crony capitalism is believed to arise when political cronyism spills over into the business world; self-serving friendships and family ties between businessmen and the government influence the economy and society to the extent that it corrupts public-serving economic and political ideals.
