Do the (low or high) expectations friends or family have for their children ever shock you?

I have a good friend- she and her DH went to an IVY for undergrad and are both MDs. Both of her kids have struggled. One completed a 2 years school and has been under-employed for years. She is now in her early 30s and I believe has finally gotten a better opportunity on the west coast. Other child did complete a 4 year degree but works in a factory. He has had some MH issues. Both continue to be subsidized by parents. They have tastes that exceed their income, and parents fill in the gap. I wouldn’t do that , but its not my choice.
