No, because I'm a selfish prick.
Really though, the thing is, when you do something to make the world a better place, like volunteer work, you get that nice feeling that you did something good today. Getting that good feeling might not be the reason why you do these things, but it is a payoff for your work. I don't get that good feeling, so what I'm left with is spending my time doing something I'm not enjoying and just having a shitty time doing it. It's just work with no pay of any kind, and I'm not doing that.
If I'm going to be nice to people I need to do it because I want to. Otherwise I just can't be arsed to put the effort into it.
