Here is a good summary and analysis from Megan McArdle, here is one key part:
But while there are a few things to like in this bill, overall, it’s a mess. All of the problems created by Obamacare’s architecture remain, and some of the problems will get worse, because lower subsidies, higher deductibles and no mandate penalty probably means that a lot of people will exit the exchanges. Those people are likely to be the folks we most need to stabilize those exchanges: healthy youngsters who don’t use much health care. Which means that the exchanges will be at further risk from the death spirals we’ve already seen in some states.
I agree the bill is a bad idea. That said, I do hope you keep in perspective some of the more, um, lurid critiques running around, including from health care economists (the Great Firewall won’t let me link to Twitter, and right now VPN is down). You can read them as sociology, however, with a rather chilling effect.
