Exactly! And while a well off person may have a memory of a time in their life when they were not doing well (like in school, starting their career etc.) that can be misleading. You tend to end up like your parents more then was true three or four generations ago for many reasons: tax policy, less physical mobility, people tending more to marry with similar levels of education or income.

People debate how much social mobility there is in the US, but it seems pretty clear that the trend has been toward less mobility. The founding fathers of the US did not want to replace one aristocracy with another. Obviously there are some who think the change makes sense-- not me.
