The answer is: up to a point. Social mobility imbues a sense of fairness that born-rich people lack
Richer people tend to be more rightwing. You’re less into redistribution if you’re the one being distributed from, rather than to. This probably isn’t a shock.
But what about social mobility? How does doing better than your parents shape your views? That’s less clear, in part because those who have been upwardly mobile tend to have higher incomes. The task is to disentangle the direct effect of being mobile from that of being richer.
