If we don't want the world's wealth to be controlled by people with money then the alternative is to have the world's wealth controlled by people with guns. Governments have plenty of guns. The theory of this is quite good. The robber puts down his pistol, picks up the ballot box and steals from rich people instead of from you. But the reality is different.
Wealth is good.
Everybody knows that about his own wealth. If you got rich it would be a great thing. You'd improve your life. You'd improve your family's life. You'd purchase education, travel, knowledge about the world.
