What about 'unfairness' in the other direction? Anecdotally, I know plenty of people born into upper (or at least middle) class families who have made impulsive or bad decisions: not working hard in university or at their jobs, abusing drugs, getting DUIs, etc.. Almost all of them are "succeeding" despite their bad choices. Lack of social mobility can mean it's difficult for poor people to rise above their station, but it also means it's hard for the rich to screw up badly enough that they suffer real consequences for their mistakes. You say no hardworking, disciplined, motivated person should live in poverty, but what of the lazy, undisciplined wastrel offspring of the upper classes? Should they live in [relative] luxury?
