The system that allows very wealthy to exist is also the reason the US has the highest class mobility among western nations. Also, on a purely pragmatic note, capital is mobile. If you penalize the rich, they just move, and then the new system will stop class mobility.
I don't know how you came up with that statement. It certainly does not reflect reality unless you don't count Sweden, Germany, Canada as part of the western world. >Individual studies have estimated absolute mobility rates for recent cohorts of roughly 50% in the US (Chetty et al. 2017), 53% in Canada (Ostrovsky 2017), 70% in Germany (Bönke, Harnack, and Luthen 2019; Stockhausen 2018), and 77% in Sweden (Liss, Korpi…
