A lot of cheap countries provide good healthcare for a fraction of american costs. Also, not sure why one need a safety net when they already have a stable income which is multiple of what any such net can provide.

Very true. This is a very big reason I left the US in my 40s, while I'm still working and can acquire permanent residency and later citizenship by having a job with a local company. I didn't want to be stuck in the US when I'm at retirement age and healthcare costs are unaffordable even with a decent nest egg, where a major procedure could wipe out all my savings.
