That’s my favorite placard from the Washington tea party protests on Saturday. No Child Left a Dime underlines perhaps the central concern of the protesters — the ongoing massive fiscal irresponsibility in Washington by both parties.

We’ve got deficits of more more than $1 trillion for years to come. Federal debt will approach World War Two levels within a decade. Even so, the Democrats are trying to ram through a $1 trillion health care expansion, and the head of the Republican National Committee, Michael Steele, is defending against any cuts to Medicare, the program that is the single biggest threat to taxpayers. People are marching not just because Obama and the Democrats are scaring their pants off, but because most Republicans in positions of power are spendthrifts as well.

The chart illustrates that no child will be left a dime because the government will have it all. This is the CBO’s “alternative fiscal scenario,” which essentially means the business-as-usual scenario if Congress doesn’t cut anything in coming years.

Note that the most rapidly growing box, the white box, is the program that Michael Steele doesn’t want to touch. The program is expected to grow by 6.3 percent of GDP by 2050. In today’s money, 6.3 percent of GDP is about $900 billion a year in added spending. So it’s like Steele doesn’t see anything wrong with tomorrow’s young families forking over an additional $900 billion a year in taxes on this one program, or about $7,700 a year for every American household.

It’s worse than that. The biggest box on the chart by 2050 is interest on the government debt, and by far the biggest contributor to the growth in interest is Medicare. So including interest, Michael Steele’s (ridiculous) Medicare position is sort of like supporting a more than $10,000 tax hike on every young family for this one program.

Come on Republicans, you can do better than that. How about starting simply by proposing some of CBO’s modest and commonsense Medicare reforms like raising deductibles?

(By the way, interest costs rise in coming years because of an excess of spending, not a shortage of revenues. Under this CBO scenario, all current tax cuts are extended, and yet federal revenues still rise as a share of GDP over time above the historical norm of recent decades).
