Imagine if we allowed insurance companies to compete across state lines, and bought plans for people upon birth. In such a case, most pre-existing conditions would be eliminated. If you add with that some basic legislation that forbids insurance companies to drop people in most scenarios it would allow the government to focus on the truly "uninsurable" rather than the "uninsured." That number is much smaller, much easier to manage, and would be much more cost effective in my view.
It is not that people do not want to see reform, they simply do not want to see this type of reform in my opinion.
