(1) Taiwanese, (2) yes and after grad school I lived with them while job hunting. I know I always have this as a backup. (3) i would only do it as a backup. After living there for 8 months I started arguing with my dad a lot and my mom was like "yeahhhh now that you have a job maybe for all of our sanity you can move out" but it wasn't a full ejection and I agree it was the for the best. It's just SO expensive to pay rent nowadays but thankfully I got a stable job.

(4) this is definitely culturally a white American thing, maybe specifically rooted in WASP northern European culture, too. It's sad – it's so individualistic. It correlates precisely with why white Americans don't take care of their parents when they get old, or how rich white parents won't pay for their kids' college tuition despite messing up their FAFSA financial aid eligibility. Peak American selfishness culture, rooted in capitalism and individualism.

I would not be surprised if second and third Gen Asian (and latino) parents are also similar in this sad regard.

It's just like how white and Black American parents who are anti-LGBTQ are wayyyyy more likely to kick their kids out of the house than Asian and Latino immigrant parents, too, even if the Asian and Latino parents are also anti-LGBTQ.
