True monopolies arising in a capitalist society are extremely rare provide examples if you think I ' m wrong . Corruption as you mentioned is by definition anticapitalist because it requires collusion with the government to obtain economic advantage . True capitalism requires voluntary exchange between producers and consumers . If that disappears or is obstructed in any way , you have left capitalism behind . You cannot have a ' mixture ' of capitalism and a planned economy . The distortions of the latter will always interfere with the former . As Ron Paul used to compare it , ' you can ' t just be a little pregnant . You either are or you aren ' t '. Unfortunately , the vast majority of the public have no idea what capitalism actually is . Go read Rothbard , Hayek , and von Mises Austrian economists . They lay it out beautifully , regardless of if you agree with them .
