But once the white young man realizes that, what would his choice be?
1) Opt out of everything, watch porn and play video games.
2) Beat the rest of the population on whatever playing field he got: excel in college, compete your way into the upper middle class.
3) Work to change the culture that is dumbing him down.
Those who choose (1) should be, at least, reminded that (2, 3) is available. Not guaranteed success at (2, 3), but a fulfilling life doing (2, 3).
#2 just has him paying for other peoples’ children (and if he excels in his field, he is supporting people a lot less motived/driven than he is).
I believe many of them are already doing #3; Trump has a nice lead in that demographic.
