Why would we try to make it work when it has failed so many times before?
The great thing about Democracy and free enterprise (Widespread Personal ownership of property) is that is relatively new and untested: it's not perfect, but it does appear to be working for the most part...I'm not starving are you? Would you give up ownership of your property to the state in return for a guarantee that you will never starve?
I wouldn't. At some point it might be in the state's interest to starve me.
