Cost is the key thing, and that's a great point to bring up. Yes, healthcare costs a lot. But that doesn't mean that those needing healthcare are to be punished. It means that costs need to be controlled.
That, to me, is the largest swing-and-miss of Obamacare. Most everyone agrees that some reform was needed because costs of healthcare are outstripping consumers' abilities to pay for it, but instead of figuring out a way to help rein in costs, Obamacare simply says, "You have to cover everyone." That's nice, but it doesn't fix the problem.
I'll be the first to admit I don't have the answer to healthcare costs. But the current political battle is no more likely to solve the problem than Obamacare did. And meanwhile, we live in the most prosperous nation on earth, yet a huge chunk of our population cannot afford the basic healthcare offered by countries half as wealthy as us.
