The idea of having affordable health care as opposed to being told sorry but you must just go die someplace as quietly as possible does tend to make it more than likely it will succeed.
Too bad for you 0bamacare's shaping up to be anything but affordable. Even that is assuming they can crunch the numbers, which isn't a valid assumption either.
On an anecdotal note, my employer switched from a PPO plan to an HMO plan to keep its costs somewhat under control. You have the option to stay in a PPOish plan, but it now costs about 4x what we had previously been paying. I switched to this plan to keep access to its better network in case my wife had to quit working and go onto my plan; her oncologist is available through the PPOish plan, but not the HMO. (She's since passed away. :-( Now that it's just me, I might suck it up and switch to the HMO to save some money. So much for "if you like your insurance, you can keep your insurance.")
