Political correctness and social good may be related, but they are not synonymous.

Ok, but that's not what he said at all. He said it's a safe investment.

One literally defines the other, so no. Unless you are speaking from a universal perspective, which unfortunately isn't really part of the collective consciousness - and therefor inconsequential to daily life and the issue at hand.

They are completely orthogonal. Social good is the "quality" of being good for society. Political correctness is almost always a complete waste of time for any society.

Do you mean to say that political correctness defines social good, or that the social good defines what is politically correct?

I'd say the former, but it really doesn't matter - the point is the subjectivity of collective "good" and "correctness". Also, a lot of people are under the impression that these things are numerically based - the democratic tyranny of the majority... this is not the case. We see the same thing play out in the slow failure of competing interest to guard against lobbyist abuse, it is an issue of motivation - not quantity or legitimacy.
