Observing American health care firsthand thanks to ill relatives, I can say that it still functions but it is probably a few years at most to collapse. Centers for Medicare and Medicaid Services budget is about 15% funded and getting worse each year. Wait times for specialty appointments are months, surgery a half-year at least (unless urgent/life-threatening), care impossible to access -- many people have to go to the ED just for diagnosis. Life expectancy down significantly in the last 10 years. We won't escape Canada's fate.

The homeless population increasing in a geometric ratio is something I have also seen in the USA. Luckily it has been a very mild winter or we would likely have large numbers of people freezing to death here as well.
