Well it’s not that it means nothing to me, but my job in the US pays about $30k more than it would in Germany (I can’t speak to other countries). Lots of Germans come to the US to work in my field for that reason (well they used to before all the layoffs). Also my health insurance is free.
That said, I absolutely still want public healthcare. Not just for the people in my country who desperately need it, but for myself too. Because while my healthcare is “free”, it isn’t really; my salary could be higher otherwise. And I lose coverage if I stop working (actually not really we have programs for that, but still kind of).
