That much is complicated. In the SF Bay Area, predominantly South Bay, I knew Asian families (all of them well-to-do, because South Bay), whose parents and extended family helped the new grads buy a house after a few years out of college.

Then those kids were expected to help the next generation, when the time came. It was like a multi-generation, extended-family economic collective of sorts. I didn't know what to make of it. On one hand I admired the effort, on some level. On the other hand, I think it really gimped the kids as far as pursuing entrepreneurship goes.

But hey, at least they can afford the "rent" in South Bay, I guess? I have never wanted to live there, so I can't say I envy the arrangement.
