Everyone is calling out (rightfully so) the divisive bait but I think there is some interesting reason worth discussing behind this:

Some Gen Z folks used the wisdom of millennials and just said fuck it and checked out, their lives might not be great but it’s probably stress free.

Whereas for millennials, in theory having the American dream was possible, just less likely as time progressed. They are stuck with an almost sunken cost fallacy in which they have tried so hard cause they believed with enough effort they would make it. Now that they are burned out, they are faced with the dilemma of either stop trying and waste the high efforts or keep going and maybe they will get lucky.

So in conclusion, millennials having it better can backfire in some sense.
