Yes and no. Less lonely than living by yourself and you can cook in bulk, but also you get sick of your family after living with them for a while. Also if you're cramming 3 generation into a 3 bedroom because of financial constraints that's pretty rough.

Sure, but specifically in a culture where it's overall disadvantagious to still live at home as a young adult: Not really, ya know?

I love my parents, but I've been ready to live separately from them for a long time.
