Humans are good at compartmentalizing. The same father that shouts at a ref over a bad call in a tee ball game will happily support industries that will give his child cancer as long as he doesn’t have to think too hard about it.
Profit is amoral. If we want a fair and just society, we must ignore profit motives and accept the cost of being civilized. The capitalist will demonize unions and taxes and regulation, because those things cost the capitalist profit. And the capitalist is right, those things are the enemy.
Unfortunately, the capitalist has also convinced everyone else that we’re supposed to be on his side. The capitalist is not on our side.
