Because it's not just money. It's time and money. You can have lots of money and nice things, but if you don't have time to raise your kids, you can't do it. And if you had the time, you wouldn't have the money.
If you have the money you hire help like a nanny. I know plenty of families who have a nannies to help with their children.
