If things generally worked out very well for you, it feels good to believe you got there because of your virtues, and that those who didn’t got there because of their vices.
While I do agree with your opinion, I think the opposite is also true. It feels good to believe you didn't get there because "The game is rigged", "You have to be born lucky", "The house always wins", etc, etc. This defeatist/powerless way of thinking may in fact make it worse for you. When hope is lost, what's left?
That is what all societies are finding out right now. Before, they could count on women having babies providing a need to hope, but now that children are optional, societies don’t seem to have a replacement mechanism.
It’s the narrative of least resistance.
