Its worse than that. The CBO scores the first ten years, which assumes 10 years of tax revenue and 6 or 7 years of expense. Remember, the taxes are frontloaded, but the implementation of the bureaucracy and the delivery/takeover of medical services starts in 2013.
So, CBO looked at the first ten years, but it was a stacked deck. Once the program goes to steady state, there's a 30 to 35% underestimate of how bad it is each ongoing year.
That’s common knowledge compared the the fraud I am talking about.
