Interesting that so many people define "rich" as an income level. Many "rich" families would be homeless if their incomes were to cease. Many "rich" families have debts (mortgages, car payments) that overwhelm their assets. Having a nice lifestyle is not the same thing as having wealth. Having a mortgage is not the same thing as owning a house (or apartment blocks or companies).

The Upper Middle Class has to play the meritocracy game to insure the lifestyles of their children because their children will have to work, but the truly wealthy are fine with the "gentleman's C." Their children can live off their investments.

So, this article appears to be comparing Upper Middle Class children with slightly more disposable income to the Middle Class with slightly less. I'm curious if this investment actually pays off in their children's lifetime earnings (rather than just getting into better schools or having higher test scores).

Is there an article on that?
Or an article on actual wealth-based educational outcomes?
