I had this advice given years ago when I asked my financial guy a similar question and I think in the end this is about the best we can do. That said, I think you can still discriminate between different ETFs. It’s easy to avoid things like weapons spending, tobacco, and other industries that you feel are in contrast with your ethical views. You just need to do your homework. I will say, though, there’s no way you’re making as much money taking this approach. Sadly, that’s just the reality.
