Here in Australia employers have to offer several choices of investment plans for superannuation, and ethical mutual funds have sprung up as a result. You can pretty much invest ethically if you want. You're still stuck with the problem that you don't get to define what "ethical" means though, you usually have to accept the mutual fund manager's definition. The other problem with ethical investing in a constrained universe of stocks is whether you are inadvertently increasing risk (i.e. price variance to benchmark) by the selection constraint. I'm not up with the latest research, but by the early 2000s there were sufficient ethical funds in the U.S. to pretty much ameliorate that risk and I'd be surprised if it was a real factor today for the U.S. (I don't have the latest data for Australia.)
