From a story on the suspension of the "Cash for Clunkers" program...
"If they can't administer a program like this, I'd be a little concerned about my health insurance," car salesman Rob Bojaryn said.
Now one could argue that the program was underfunded to start with, which leads me to ask "how could the government not know it was underfunded?" It comes down to not understanding the x factor. x being demand in this case.
Project that kind of mismanagement to health care and you have chaos. Consider the fact that there are many x's in health care and you have a complete disaster.
Once you get beyond on the morality plays, you begin to see just how unsustainable government controlled heath care will be.
