@Mor - There are more than enough watchdog organizations though, who do all the dirty work of assessing companies to see where they stand on all kinds of issues. Yes, it's a difficult thing to evaluate. I mean, I doubt there is a single company on Earth that hasn't done something wrong at some point.
But there are enough guides out there now that I really think people who go for wealth maximization strategies over everything else are basically bad people. There's no excuse. You can make money and still invest ethically, and anyone who says otherwise is wrong.
