So this is just moving goal posts IMO. End of day it's harder to go from the poorest to the richest. Speaking as someone that was born below the poverty line and but later was earning in the top 1% in the USA, going from sub 14k to 36k was gigantically huge...going from 50k to 250k in as short of a span didnt affect me very much, but moving to France and not worrying about medical bills or insurance companies again was a game changer ... YMMV and everyone is different
