The fact is if someone works for one of those companies, they are contributing to the problem. Maybe out of greed, maybe necessity, maybe ignorance. Moral judgements aside, it really doesn't matter why as long as they choose to work there - the company still benefits and the cycle still continues. I'm sure teaching ethics would help.. but then again I don't think all the recent revelations about FB/Google/Twitter have done anything to make hiring more difficult for them. At most they pay 10-20% more and get the people they need. Parts of wall street are unethical and yet they get all the employees they need given the right salary.
