For clarity, I'm not that hung up on the capitalist standpoint
When 45,000 people are dying without healthcare, I don't need the capitalism argument to motivate me but for those running into the socialism rebuttal, it might be handy. I do believe in the economic benefits that I pointed out though.
Obamacare isn't a perfect solution. Single payer has flaws too but I think it can work pretty well.
The big thing about Obamacare is that it's going forward. They don't have to try to get a 60 seat majority in the Senate, a majority in the House and a sympathetic president to go through that terrible argument again.
When America finds out that there are no death panels, etc, and see some encouraging numbers in health care costs, I think Obamacare will appeal much more over time and it will become more like Medicare - they won't be able to get rid of it. And the focus will become how this imperfect legislation can be improved - which will likely move it towards Medicare for all - with a few stages of amendments.
