I said greed for money makes us bad humans. Not money.

There is absolutely nothing wrong with "not wanting to impact the world", and it's a shame that so many are implying that it is. It's "enjoying life", plain and simple.

I don't care about money; I let it run out a few months ago. Didn't phase me. I simply got a job when I needed to, and now I have $11k saved up. I'm very lucky to be a programmer. But more than that, I'm lucky to be able to enjoy life by studying as much science as I want to. Does that make me a bad person? By your implication, it does, because I don't care about money, and spend it freely.

On a different note... It sounds like you've been through a struggle, and came out stronger. I just wanted to say congratulations. I respect that a lot.
