Greedy destructive bastards. Ever tried arguing with a Libertarian?
You can't really, because there's no shared ground. For you or me needless human suffering on a massive scale is a bad thing, something we should actively work to avoid. But if someone genuinely doesn't care about that just so long as they personally can do whatever they like, where do you even start?
I might try and point out that wealth hoarders don't actually tend to be very happy, and that they never get to the point where they've hoarded enough and can relax and enjoy it. Which is true, but it'll never get past the layers of denial. You'll get a stock response, usually 'you're just jealous' which again comes from a place of not sharing any basic values or objectives with the person they're talking to.
