Sane people who recognize that either extreme on the scale is not something to be desired, or which will enjoy significant success in reality. A true laissez-faire capitalist system would see the concentration of economic (and by extension, political) power in the hands of a few monopolies, and thus a few people. Even Adam Smith recognized the effects of these on the invisible hand and recommended against the monopolies of his era (government-funded mercantilist systems), and even America, arguably the most strongly capitalist nation in the world, instituted many anti-trust acts to prevent such a concentration of power, as well as (eventually) allowing the peaceful growth of the labour unions (or rather, forcing the companies to accept it ).
