Free-market capitalism is a network of free and voluntary exchanges in which producers work, produce, and exchange their products for the products of others through prices voluntarily arrived at.
The only trouble with capitalism is capitalists; they're too damn greedy.
People feel they are not participating in the decision-making process. Decisions are exclusive to those at the very top. You have grown up with crony capitalism and it creates ever more resentment.
Capitalism is war; socialism is peace.
The advantage of the free market system is that people invest their capital, they create jobs by investing their capital, and hopefully they get a return on that investment. I don't think there's anything wrong with good old American capitalism.
