Democrats have implicitly agreed that Obamacare is broke

And, it fricked everyone else as well. Nothing they do ever works.

The problem with Obamacare was it provided a temporary bandaid to alleviate a real problem with healthcare insurance as a model for affordable access. The insurance model does not really work because insurance is a gamble by the two parties involved but the insurer is always going to lose on the balance because very few people live without at least one major, expensive health episode. However, since they're going to lose the gamble but still need to make a profit, they have to degrade service or deny high-risk customers.

If we didn't have Obamacare, the insurance industry would have eventually started turning down policy writing for the state-assigned risk pools. People with pre-existing conditions that insurers didn't want to cover would start going without insurance. With that acceleration of the buckling of US medical care, we would have to reckon with the essential problems with how medicine works in this country.

As a person who would like a more "progressive" (in the this system isn't working and isn't ever going to without a radical change way) reckoning on this front, I think letting the GOP actually gut all provisions of Obamacare would be preferable. It would lead to more creative thinking on the problem. It would suck shite for some sick people in the interim unfortunately but that broad social pressure may uncork some possibilities that a tax money bandaid won't.

Where did you find that it costs a trillion per year? Everything i find says it's less than a tenth of that.

Then why are they continuing to block the reopening of the government?
