The point is that it's never executed well. Socialism sounds great on paper when people are perfect. But they are not. They never will be. It will therefore never be "done the right way this time" and we will keep using it as an excuse to worsen peoples' livelihoods equally, decrease peoples' income with which they decide what they want to use to pay for, and to put down dissidents. As it always has.

Capitalism is the worst type of economic strategy, except for all the others.

"The inherent vice of capitalism is the unequal sharing of blessings; the inherent virtue of socialism is the equal sharing of miseries."
