If you work in China, you get their universal healthcare but you still need a private insurance policy. It’s hard to explain though, you wouldn’t be completely up sh*t creek without a private policy, but some things become really inconvenient, and the standard of care is different (bring your own nurse in the public plan).

China sort has welfare but the hukou system means most people who need it don't qualify in the city they live in.

No? Chinese people have to work 6 days a week for a lower quality of living than a minimum wage American.

No they don't:

If you work, you automatically get enrolled in a hybrid healthcare system (state+private)

If you are young or elderly you get automatic coverage.

If you are working age but have no job --then you get basic healthcare (not comprehensive)

Lots of people who can afford will buy private insurance on top if they have a serious illness (basic healthcare is not comprehensive)

Also copays and high deductibles. People can end up footing 20 to 50% of their medical bills (out of pocket).
