The idea of a free market scares control freaks and the greedy, who want the deck stacked in their favor by the controlling authority that they bought.
Free markets and capitalism are not a panacea. Even Adam Smith saw the need for limited government and even lawyers.
It is the limited we argue about. Time to swing much more the other way to less govt. But as I said, it is scary, that is why most people are workers and not self employed.
