As in, what about that campaign promise Trump made to "repeal and replace" the ACA....which Republicans loved because they'd tried unsuccessfully to repeal it over 50 times? I'm still waiting for the "replacement" ideas. No, it's not enough to say It'll be totally great, fantastic, people will love it, trust me!"
It's a given that a single payer NHS is dead in the water, as is a Medicare-for-all type system, and the latest expansions of state Medicaid will likely be undone, too. My guess is congress will undo/void the individual mandate, which will make the whole thing implode. But they'll still use the private insurance model to mean "healthcare", which will mean we'll go back to millions of uninsured people (who use ERs for healthcare), and millions of under-insured who'll have to declare medical bankruptcy (after their first disease or accident). And none of that will help reduce or contain the costs of medical care.
Any predictions or policy preferences you'd like to see moving forward?
