Tools can be used to do harm. You can hit somebody over the head with a shovel. But tools are still good. You should give some of your saws and planes and nails and chisels to the man who's cooking omelettes. Wealth brings great benefits to the world.
Rich people are heros.
They don't usually mean to be but that's their moral problem not ours. Most of the world now admits that free enterprise works. Economic liberty makes people rich. But in our residual collectivism and our infatuation with equality we keep trying to get rid of rich people. When the family gathers to eat there's a pig seated at the table.
