People do not want “pure” capitalism. Caveat emptor are the words you do not want to hear. It means that if you buy a quart of milk and a loaf of bread, you take it home and find the bread is stall and the milk is sour, you have two chooses. You can throw the milk and bread away and learn not to go back to that store, or consume the food and hope you do not become sick or die.
A “perfect” capitalism has no welfare moms or food stamp recipients because there are no social programs. I do not think that will happen. It means no taxes and politicians would perform their elected duties for free.
Also, “pure” capitalism opens the marketplace even wider. There are no illegal businesses. Drug dealers and/or prostitutes can open a business on any corner block or business’ parking lot. There is no laws making it illegal, no police to enforce the non-existing laws, and no courts to act on fantasy laws.
It also means no minimum wages. The pay has a “floating” value. Anyone can work for 50 cents an hour serving your burger.
