The ACA is not good. But it's an awful lot better than what we had before.

The problem is in the old days we had a fake "insurance". This wasn't a problem with cheapskates, but with how the industry worked. Companies would offer a plan for a little while, only let healthy people in, premiums were reasonable. Then they would offer something a tiny bit different, give it a new name. As time went on the people on the old plan would develop health problems, premiums were calculated based on what THAT PLAN had to pay out, so premiums went up. Healthy, jump ship to the new one. Not healthy, you can't. The old plan would soon go into a death spiral and you would be uninsured.

Thus anyone with a chronic health problem was stuck.

And they're trying to bring back the old days. Allow other health insurance to be sold, the healthy people will jump to it and the ACA will death spiral.

We did get the unexpected result of exposing the large number of people with "insurance" that was basically a scam. A lot of people didn't know they had policies that had insanely low limits or the like. I'm thinking of a post from back then, a student health plan that had gone up like 10x, "where's the difference?" And a bunch of people who couldn't understand even when I pointed out how the cheap version was effectively worthless for anything that needed more than a doctor's visit.
