That is interesting, I have had the exact opposite experience.
and I'm not saying it's necessarily a bad thing to have parental assistance past a certain age. It's sort of an American thing to expect the complete independence compared to other cultures that have more inter-generational living. Can be pretty nice - parents help with childcare/running household and have care as they age. But the attitude that I see with it in my experience is almost a sort of obliviousness.
I had a relative ***** because my mom bought me granola bars and cereal over a college break that I took back with me. "You're out of the house now, you shouldn't be getting anything. You're on your own". Literally over $40 in groceries that I was very grateful to receive.
Same person today? Living in their parents' rental, rent-free and got pissed when parents wouldn't agree to provide free daycare for their child. On parent's healthcare until 26. Probably still on parent's cell phone plan. But extremely conservative politically (so definitely no college tuition help, Medicare for All type stuff) and would have no problem ******** about the idea of urban millennials living with their parents/still getting help from them. And I know a pile of others back home who would be just like that.
