The only solution is living on a farm and completely isolating yourself from everyone. You also can't use any products or services produced by anyone because the chain of profits goes the other way too.

Short of obviously bad companies (like those selling cigarettes perhaps), most companies are mostly doing good things for mostly good customers who are mostly trying to do good things and so on. I know a good number of people and while some might be a little greedier than others, and some others are disorganized and get themselves into situations where they are desperate and do something not great, none of them are genuinely bad people. Some of the very best people I know work in ads, and some of them at Facebook.
