The biggest disappointment about the ACA is that the discussion completely ignores the cost of care.
In other words: the healthcare discussion in America revolved around "how can we make it so everyone can afford this $300 asprin?" rather than, "Why are we letting hospitals charge $300 for asprin?"
There's a simple reason they charge whatever they want and generally can't even be bothered to disclose those prices ahead of time: because they can.
To critics of the ACA, the relevant question is, who or what is in an effective position to put downward pricing pressure on hospitals? Because to date, it has clearly not been individuals or insurance companies.
Single-payer systems have a track record for being much better at putting downward pressure on pricing. Not only can they secure drug discounts of ~50% due to their ability to bargain as a bloc against much smaller insurance companies in the US, but they lack perverse incentives to allow costs to rise. Insurance companies don't care about reducing costs, only reducing costs relative to competitors. Since their "cut" is a fraction of overall expenditures, they're quite happy to see costs rise, as long as they rise in tandem for their competitors.
Nobody who is familiar with the market is surprised that single-payer systems are so much cheaper.
> they lack perverse incentives to allow costs to rise
But, of course, they also lack incentive to actually provide all that much care, so long as those who are inconvenienced are politically unimportant (e.g. disabled newborns), and they have plenty of incentive to provide more care for the politically connected.
In practice, we can just look at existing single payer systems and see how they're doing. Would you rather be a poor parent of a disabled child in the US or the UK?
The person best in the position to apply pricing pressure is the person paying the bills. Since individuals do not pay the bills, of course they haven't been put pricing pressure on hospitals.
The ACA pretty much doubles down on employer-provided health insurance that covers many routine costs, which doesn't address that issue.
In other words: the healthcare discussion in America revolved around "how can we make it so everyone can afford this $300 asprin?" rather than, "Why are we letting hospitals charge $300 for asprin?"
A very clever smokescreen.
