Good take, but I think it ignores a lot.

We're stronger, wiser and ultimately happier for it, despite outward appearances

Mainly here. Yes everything people are getting is from their own actions, but it completely ignores the people that haven't gotten anything from the struggle, which is a growing number of people. It also disregards people that don't have the opportunity to carve their own way at all.

There is still a bar that needs to be met to get anywhere, and it is just getting higher in may places. Sure once you hit the bar, you're in a better spot and can see that the struggle paid off, but if you never get to the bar, if you never get to the point of "keeping your head at the water", there is no payoff. These people just get to struggle. That's all there is, and there is only so much of that before the struggle isn't worth the payoff anymore.
