Though I should add, never give up on your principles. We may have to make compromises with ourselves because we live in a society in which it costs money to live. Your job isn't your identity though and there are some lines which aren't worth crossing.

It's also hard to sustain a career in this environment alone for long periods of time. Consider your relationships as your most important asset. And consider organizing.

Differences can be made. Programming computers won't get you there. It will take some changes to the social environment around you.
