True in theory only. UK has had 100s of generation where they had already made it and had the wealth, but they kept going at it. it is only in the last 2 generations after WW2 that kids in UK just do not want to work anymore.
Quote from peilthetraveler:
Works like this...
1st generation: goes without so their kids can be successful
2nd generation: Is successful and makes lots of money.
3rd Generation: Lazy. Just lives off rich mommy & daddy. Why work? Their parents are rich so the kids have no drive, especially if they are handed everything on a silver platter all their lives.
4th Generation: Has nothing. Goes without so kids can be successfull.
