Corporations are not possible without state and true capitalism is not possible with state.
Also people can not be free in any state and all states collapse always.
State do not work in theory nor in practice as we can see.
Firms are possible without state, free market, real defence, real education, real economy etc.
Only negative aspect I have managed to to find and still worries me is the fact that overall comfort and richness tend to make people lazy and activate genes what are responsible for not so progressive behaviours though I think that can be avoided by better self control and logic.
Socialistic arguments so far have been all faulty and non logical therefore impossible in real life.
