It's virtually always impossible for almost everyone to be able to simultaneously 1] have kids while you're still young 2] wait until you have "enough" money.
Warren Buffet's quote doesn't make sense, because both "anything" and "nothing" are relative. You can "do nothing" with extraordinarily little money. You can also not be able to do "anything" even with billions of dollars (start an asteroid mining company?).
If you give your kids the moon, you just have to make sure they still have motivation and character, it's still possible. Not everyone who inherits money is a layabout.
I can stop now though, I think we just fundamentally have different opinions on this and probably won't budge much.
