Does Social Investing Get Results?

I remain foggy about how social investing changes corporate behavior. By what metrics has all this social investing succeeded in doing anything more than moving money to one set of money managers rather than another, or from one set of funds inside an investment company to another set of funds? Can any money manager show that a single Fortune 100 company has been fundamentally reformed through the manager's efforts?  Proof is not needed of results because social investing is an exercise in hypocrisy. Truly, we want delusion. We want to buy stock in companies whose price goes up and we want the delusion that we are good people. We are like consumers who eat red meat, but prefer not to see the butcher's bloody hands.
