I think you're being overly dramatic.

Nate Silver has some good numerical analysis here: http://www.fivethirtyeight.com/2009/12/why-progressives-are-batshit-crazy-to.html

I don't think that US government debt has much connection to reality any more. The international macroeconomy wizards seem to make things work. Given their track record, I am confident that the financial wizards can continue to make a fundamentally unsustainable balance sheet sustainable, at least until the Singularity.

So I think that the marginal increase in debt from the bill is a smaller risk to the stability of the USA than maintaining the very flawed status quo of healthcare in the USA.

Useful question: When does the bill go into effect? My parent's insurance is kicking me off at the end of the month and it will be nice to be able to stay on it for a few more years.
