I just looked at the local marketplace plans. The absolute dirt-cheapest I could do for my family is ~$1,225/month premium with a deductible of $13,400 and out-of-pocket max of $21,200. Most of the structure is some form of "zero help until the deductible, then I pay 20%-40% of everything up until the OOP max". In other words, I'm being asked to buy a product, and the cheapest form of it is to basically pay almost $1…
It was never sustainable. Because the model relied on healthy people subsidizing the people who make extremely poor choices (obesity, smoking, drugs or a combination of that). Obamacare's modeling predicted that significantly more healthy people would sign up, driving costs down. It didn't happen. Now it is a system that ONLY the unhealthy benefit from. Everyone else pays for extremely bad choices.
That's because the GOP Congress gutted the provisions that heavily incentivized healthy people to sign up.
We could also just do Medicare for All. Every other developed country seems to have figured that out but us :/
