D'Amato on Economic Fascism and the Power Elite:
"In the present day, following the maturation of the connections identified by Mills, Rothbard, Higgs and others, the economy has been “centralized . . . into a highly structured bureaucracy under the effective direction and control of leading business interests.” We can in no way be said to have a free market, as the ties between powerful interests and the federal government are as strong as ever. Politics is an expensive, high-stakes game of favors and bribery, a fact that libertarians like Comte and Dunoyer saw clearly hundreds of years ago."
This is the summation of what he wrote in the rest of the linked article. Informative, useful reading for those who need to demonstrate that we do not have a free market economy.
What we have may be called "capitalism," but this is a word that has too many meanings. I prefer "free market" to describe a free market, because using the C word doesn't really clarify.
I hope you enjoy the article, and find the references useful!
