Michal,
That is definitely a common misconception. One that even I had. True
capitalism (free market) requires the respect of private property above and
beyond respect for the state. As such, partnerships or special privileges
granted by the state are not, in any way, associated with pure free market
capitalism. Really good examples are writings by Hazlitt, Mises, Hayek,
Smith, and a great many others.
Subsidies, favouritism, monopolism (through patent, copyright, etc) are all
features of crony capitalism (or cronyism). This is a capitalism that is not
honest enough to be socialism. :)
In philosophy, I am nearly an anarcho-capitalist.
