"They believe if you’re not a millionaire, or well on your way to becoming one, then it’s your fault. They think you made poor decisions, or that you’re lazy and entitled"

Its a religious behavior inherited from Puriten Christianity: Faithful work hard, therefore get 'saved' (get rich), whereas the heretics wither in poverty. So if someone is poor, it must be because they are sinners or heretics.

Its religion, really.
