I'm not sure why you think that this is political correctness. There's a clear representation gap in employment at high-wage jobs for large portions of the population. And, that's a social issue that has been identified. As a society we can then either ignore it or address it.
I get that you have a strong opinion on why that gap exists. And, you have opinions on which things won't work to solve the problem. But, by dismissing the issue as political correctness, you seem to be saying that it's not something that we, as a society, should address.
And, that's fine if you believe that. We can all decide to do nothing. But, as an alternative approach, I'd ask that you try to role-play for a moment that one of these people are one of your family. Would you try to help them? Or, would you tell them to get lost?
I think that we have reached a point where a lot of people have started to view vast segments of population as 'others'. Our society seems to be turning into 'us' vs. 'them', and to me that's problematic. We have double standards when it comes to our family and friends vs. everyone else. Personally, I think that's an awful state of affairs and limits the advancement of Humanity.
