The health “care” industry is a very powerful lobby in the US and between that and the ideological bent of the Republican party, much less the MAGAts, they would never tolerate the continuation of state-level government health care except, maybe, for pregnant women (once the babies are born, of course, both mother and child can be cut loose).
Yes, US states have Medicaid and Medicare, which is the closet thing to government-provided health care the US has - but DOGE is trying to dismantle both even as we speak. In any case - you have to either live long enough to qualify for Medicare, or be Officially Disabled (my late spouse - born with spina bifida - never qualified for that so make of that what you will), or be poor… with the caveat that it’s perfectly legal to restrict that to just poor children, or just pregnant women, or otherwise severely limit access. The result being that many, many poor adults, especially men, simply have no health coverage at all. Other than the mandate that ER’s must treat you if you’re in imminent danger of death. Unless you’re a pregnant woman in Texas, in which case your fetus is more important than you are. If you aren’t actively dying… screw you. Have cancer or something else chronic and need treatment? Sucks to be you if you can’t pay, you get nothing… until the point you’re in on the point of sudden death in which case the ER is obligated to patch you up sufficiently to put you out on the street again. Then sends you a bill you can’t pay and hounds you for the rest of your life.
Another scenario - a diabetic can’t afford insulin, can’t afford to go to the doctor. Then falls into a diabetic coma, is transported to the ER, and “fixed” - then turned out on the street again. Where they can’t get insulin, and can’t afford to go to the doctor. Then fall in to a diabetic coma… rinse and repeat, until they also go blind or have to have a limb amputated. Which won’t happen until it’s a matter of lop off a leg or the patient WILL die soon… but then back out in the world again, still no insulin, no doctor, and no rehab or prosthetics and hope to God someone gives them a wheelchair. I have known two people in that situation (both are dead now). IF the person is photogenic enough maybe they can get a GoFundMe to pay for their medical care but if not… they deteriorate and die.
Against that backdrop no, provincial health care will not survive. Also, Trump has repeatedly said he’ll “save” Canadians from high taxes… which is how your provincial health care is funded. So he’ll eliminate the money for it, then the US Health"care" industry will move in to impose private healthcare.
Maybe YOU don’t have a reason to believe that scenario, but I’ve lived in the US all my life and even worked for the Evil Insurance Empire for a decade and a half (at the time it was the only way to get health coverage for my family, which was sort of essential with a spouse with serious chronic health problems) and I sure as hell DO have a reason to think your Provincial health care would be doomed if the US took over Canada. Even the most progressive US state with the best Medicaid/Medicare programs is a pale, pale shadow of the worst Canadian Province health care situation.
