If The Affordable Care Act, also know as Obamacare, is really as bad as so many Republicans think, it still makes no sense to shut down the government in a last ditch effort to stop it. If it's really that bad, it will implode on it's own after implementation. While I like the idea and it will be much better for lower and moderate income people than the high insurance premiums of our current system, I still worry that it may face cost overruns which cost the government more than expected. If that happens, it could implode.
I hope it succeeds and for sure, future lawmakers can adjust it. There are also lots of budget savings in Obamacare, over the present situation, so it might just work. It might even not bust the budget.
Whatever system we have, it's still up to us to try and live healthy lifestyles as much as possible. No matter what, we can't afford unlimited care. I hope Obamacare's improved access to preventative care and lifestyle / diet counseling can reduce the amount of expensive emergency room care that so many folks rely on now.
