Bingo! All the interesting, financially-remunerative jobs these days for ambitious young people are bullshit. Not in the sense of not creating value (because I think there is value created in these industries), but because they are all open to criticism of this sort in one way or another.

Are you a rocket scientist? You probably make your money directly or indirectly from the military industrial complex. Are you a doctor? You'd make much less money if the AMA didn't artificially restrict the supply of doctors. Are you working in Silicon Valley? Your product is either based on ads, or is a side-project of some company that makes all its money on ads (e.g. Google, vis-a-vis Glass or self-driving cars).

It's not worth worrying about this shit. Do something you find interesting if not morally fulfilling, and try to make a lot of money doing it because we live in a country where your kids can't see a doctor unless you can write the checks.
