Yeah, before, insurers could throw out people who have preconditions or have “maximum lifetime benefit”, obviously you were going to pay less in premiums. The bureaucracy / cost of new technologies have not made this any cheaper either, especially as cost-benefit analysis for new procedures and drugs is, somehow, not a thing in the US unlike everywhere else in the world.

The US hates cutting costs via market intervention too (also see our crazy college costs problem), so until we decide to finally tackle it, they’ll keep on rising.

Isn't the college cost problem a prime example of a market intervention? Special case undischargable debt that only applies to student loans.

Say what you want about the ACA, but it was the trajectory of US health expenditure (vs GDP per capita) that was the problem: increasing year by year.

So doing nothing / business as usual wasn't a fiscally sustainable choice.
