In countries with government provided healthcare for all, we still do dance marathons to pay for bits of it. Ugh maybe it’s just the UK.
In my country there are multiple foundations and charity events, but these mainly aim to equip hostpitals rather than fund care. New equipment costs a lot in quantity hospitals need, and on gov money it would slowly trickle in. Meanwhile such events and foundations can greatly boost the speed of modernization.
There are aims to help with care funding, but that’s pretty much explicitly cancer cases where we need top-of-the-line treatments that are not available on public healthcare.
