As someone frequently accused of being a communistical socialist, or, worse, a socialistical communist communism lover, let we set some of you straight about the role of the owner of a grocery store in a free-market, and free, society. Stores have groceries because the owner contributed capital to the store to buy the groceries on the shelves, and pays the workers who put the groceries on the shelves. No owners, no groceries.
A similar example from the past: Stalin tried to eliminate farm ownership. He succeeded for a while, but then the peasants stopped growing the crops, and huge, ghastly famines resulted.
