Obamacare was doomed from day one. There's not a single organization in the world, public or private, that can write a bill or policy that stands 8 feet tall that would make any sense at all. It was a single party bill. It wasn't understood by anyone that voted for it. In fact, I'm not certain a single member of congress had read it front to back, much less understood what he/she was voting for.
You are exactly right. This needs to be taken in tiny chunks. Start with the five or six provisions everyone can agree on, then monitor the unintended consequences of it, then move to improve it. Something as monstrous as health care legislation might even take a generation to get anywhere near "right."
