Why are the Feds contemplating national health insurance/plan?

I have a question: if you know of someone who constantly cannot manage things and get things to work, would you continue to give them things to do or give them a huge project to work on?

If you are a logical and rational person, you would be saying "NO!"; however, why is it that with our government, they constantly say "Yes!"?

To that end, why are we even trusting the Federal government when they propose a new health care solution when they can't even run Medicare and Medicaid properly? Am I supposed to believe that they finally figured it out after decades of trying? Hell, the Feds cannot even run the Cash for Clunkers program properly....how am I supposed to believe that they can run a multi-trillion dollar health care program for every citizen in the US?

I would ask for a cautious approach. If the Federal government honestly believes that they have the right solution, let's test it out first. Have the Federal government eat its own dog food, that is, have all of the Federal government take up this program. Let it run for a decade to see if all the assumptions of the program come true. If the program meets the strict definitions of success, then roll it out to the entire country.

Is this too much to ask? Will the members of Congress, the Executive branch, Federal employees, etc. be willing to test out the program first?
