The US healthcare system is one of the most over regulated industries on the planet. Look up the phrases "Rent seeking" and "Regulatory capture"

yes, the only thing keeping them from providing a good service is that dang ol’ government stopping them from treating customers well and covering more illnesses and medications.

the fact that they’re rent-seeking sh**bag middlemen is purely because the government makes them be that.

That is delayed till 2027 to further study, so no guarantee that that will happen. A requirement for assisted suicide in Canada is that the patient has to request it, an independent observer has to acknowledge that, and two health proffesionals have to sign off. Yes, with the mentally ill it is possible that they are not acting in their own best interest. I am personally less worried about the mentally ill being treated, than all the people with mental health issues not receiving any treatment because they don't have health insurance.

And also, while we are talking about it:

The United States ranks last among 16 high-income, industrialized nations when it comes to deaths that could potentially have been prevented with timely access to effective health care, according to a Commonwealth Fund–supported study that appeared online in the journal Health Policy. According to the analysis, other nations lowered their preventable death rates an average of 31 percent between 1997–98 and 2006–07, while the U.S. rate declined by only 20 percent, from 120 to 96 per 100,000. At the end of the decade, the preventable mortality rate in the U.S. was almost twice that in France, which had the lowest rate—55 per 100,000.

Because a large majority of Americans don’t put a high priority on their health.

Do you think our current “for profit” healthcare system is working out?

2 truths can exist at the same time:
.gov is bloated and spends too much
some services should be handled by the government and not “for profit”

Or any other American's health. My choice, amirite?

what is it about americans that makes them place a lower priority on health than, say, residents of the uk or canada or chile?

It was working a hell of a lot better before the "Affordable Care Act".
