Trump has been all over the map about the Affordable Care Act since he "won" the election, stating he'd like to keep the "popular" bits after meeting with Obama, then stating he'd organize a special session of Congress the day after he's inaugurated to repeal the whole thing. (He's apparently unaware Congress will already be in session, but, whatever.) If he chooses to keep the "popular" bits, the health insurance industry will crumble, for what it's worth, because they'll be forced to provide coverage for pre-existing conditions to people who refuse to pay a penny in premiums until they fall ill.
My view is nuanced on Obamacare, so I expect 99% of the replies to this post to miss the point completely, probably just focusing on the headline, but...
That it's going... is not to be celebrated, because it means suddenly a huge number of people will be unable to afford health care. That's bad. But simply blaming Republicans and Fascists for its removal is missing the greater picture: it was insanely unpopular. It was something Republicans were able to rally around to defeat Democrats. Think about that for a second: UH should be popular. It should have been a real concern by most of the country that they were going to lose it. When in 2012 Democrats wanted the Senior vote, they pointed out Paul Ryan planned to replace Medicare - UH for seniors - and were rewarded by a shift towards them. Nobody was able to stand up in 2016 and say "Hey guys, Trump will kill Obamacare, you don't want to lose that!" In fact, the opposite happened, Trump used Obamacare against Clinton.
Why did it fail? Because it sucked. It didn't control prices significantly enough that people noticed - in fact, most believed Obamacare was to blame for rising insurance costs. Most had insurance before, they had insurance afterwards, and the insurance afterwards was still going up in price way above inflation. It was the same system as they had before, but it was more expensive.
And those who didn't have insurance before, well, they resented it. Suddenly they were forced to pay for something they hadn't been required to have before, and most people don't have cancer or require an MRI, so they never saw any value in what they were forced to buy, despite the subsidies and so on.
The Democrats, if they ever get back into power, have to decide where they want to go with Universal Healthcare. But next time - if there is a next time - there's really only one option, and that's an income tax funded single payer system. If that's not politically possible thanks to Blue Dogs or whatever, then don't address the issue - it's a waste of time, and it'll result in Democrats being unable to address any other aspects of their agenda. But Single Payer is virtually the only healthcare system you can create that people would be frightened of losing. Which makes it politically the only choice worth pursuing. And in practical terms, it's also the only way to deliver truly universal healthcare.
RIP Obamacare. I'm sorry for the people who'll lose coverage, but I'm not going to blame the Republicans for getting rid of it.
