> It is not morally wrong ("greedy") for investors to seek high returns.

This is an example of isolating an action from a bigger picture. Of course, it's not morally wrong to seek high returns - in complete isolation from how they're sought.

What's more important is how the higher returns are sought. Is the investor privatizing water? Canceling funding for services like abortion? Or are they doing things that net benefit a society like building housing, designing and researching more efficient transportation.

Therefore the means through which the investment is sought can circumscribe morally wrong investments.
