You guys pay 10% GDP like every other country who has Universal Health Care. We pay 17% GDP. In 1980 we paid 10 % GDP.
In 40 years time, health Care cost increases in the US has almost doubled the rate of inflation.
Whatever shortfalls the Canadian system has, it isn't going to crash your economy like the US system is going to do.
If it doesn't crash the economy, it will be because we ration healthcare. And rising healthcare costs are a concern everywhere, not just the USA. We are just a few years behind, that's all.
Look, healthcare is super expensive, and there are legitimate tradeoffs between systems. I think the current American system is actively bad; it has perverse incentives and manages to combine the bureaucracy of a single-payer system with the expense of a private one. I think that healthcare is very poorly suited to being privately insured.
So yeah, I support single payer in Canada, for all of its flaws and imperfections, which are multitudinous. I would prefer if we had a proper parallel private system, but a lot of people get their noses out of joint about being egalitarian, so everyone is stuck with the same level of care. Whatever. I'll work with the system as it exists.
What I don't think is that:
1) Americans will like or accept their quality of healthcare being reduced, which it will if the system attempts to control costs;
2) Doctors and nurses will accept taking a massive pay cut (they are pretty good at lobbying, after all);
3) Single payer will result in any savings. It will, if anything, blow up the system sooner, because voters will do what voters in every country do; vote for the goodies and vote against paying for them; and
4) That you can cap drug prices without disincentivizing drug research.
So if single payer happens, which I doubt, be aware that problems of access to treatment and affordability will merely
shift location, not disappear. The distinction is important.
But looking a tradeoffs is hard and scary and grown-up work, so lets all go back to calling each other names on the internet.
