We are in an economic depression. In the future, we will hardly be able to pay for social security because of population growth. And healthcare is by no mean cheap. I think you greatly underestimate the cost of this project.
It will likely be one of the most costly reforms in American history. Plus, remember that people don't like taxes to begin with -- but it's going to cost the American people a very pretty penny, and it won't be a small change in that.
I hate to say it, but people die. People will die on healthcare. People will die while waiting. It's a fact of life; you can't change that. To put rational decision-making on the back burner will not help -- you will be forever delaying the onset of death and never making the system as good or as effective as it could be. In this situation, effectiveness and rational, objective decision making is very important BECAUSE human lives are at stake; the best system would do the most humanitarian good in the long run. And you have to include economics, politics, etc in that mix, because all of those affect the quality of people's lives and their ability to live prosperously and happily. You must address that, and it's better to do that sooner rather than later.
America is, by itself, the size of Europe, and just as economically and geographically diverse. Politically so, as well. It's not easy to come up with a system of that caliber that will work well. And Americans are not dying that quickly -- in some areas, the healthcare is worse than in others, and to certain groups of people. But overall, we're not in any sort of crisis. A good part of that sense of urgency comes from the over-dramatization of the polarization in the political arguments. But it is not nearly so urgent as to allow us to succumb to passion and lose site of the rational side.
