I understand your frustration, but it's not literally nothing - just less than it should be. The US still has Medicaid/Medicare, public schools, welfare services, emergency services, etc (even if you don't use them yourself you benefit from a reduction in the number of desparate people around you if they were cut back even further than they already have).

If you are completely broke and go/are brought to a hospital in the US with an immediate life threatening medical issue, they will still try to save your life.
