The insideous thing about the terrible healthcare system in the US is not the covid deaths but all of the ruined lives that aren't counted in any statistic. Sending people bills of tens of thousands for getting tested or treated shows the complete contempt that the US has for its citizens. Contempt isn't a word that should be associated with a healthcare system and I haven't heard it in connection with any other system.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
