President Obama’s remarks on fiscal policy today put forth a few numbers worth committing to memory before the forthcoming, protracted budget debates:

“So here’s the truth.  Around two-thirds of our budget — two-thirds — is spent on Medicare, Medicaid, Social Security, and national security.  Two-thirds.  Programs like unemployment insurance, student loans, veterans’ benefits, and tax credits for working families take up another 20 percent.  What’s left, after interest on the debt, is just 12 percent for everything else.  That’s 12 percent for all of our national priorities — education, clean energy, medical research, transportation, our national parks, food safety, keeping our air and water clean — you name it — all of that accounts for 12 percent of our budget.”

Consider also a very interesting tax calculator from Remapping Debate, a publication that started showing up in my inbox a few weeks ago and as been worth a look pretty consistently. Taxes are currently pretty low, by historical standards (unless you’re talking Gilded Age).

Today I sent $4,000 to the feds and another $1,000 to the state of Colorado. Being taxed doesn’t feel good. I could only afford to put four grand in my retirement account this year. But you grit your teeth and remind yourself: taxes are necessary, because government is necessary. Taxes are quite low in Somalia, I hear, for those who want to give no government a shot. The House Tea Party caucus could do an exchange year. “Morons to Mogadishu,” we’ll call it.

Which brings me to the Republican party writ large. The idea of privatizing Medicare/Medicaid aside (it’s insane — let’s cut costs of a proven program by adding layers of private-sector bureaucracy and diluting purchasing power! At best, it’s cost shifting — rather than via government, seniors and the poor and society as a whole will pay more, just directly to insurers), the particulars of their plan are just cynical. Sure, we must cut. But taxes have to be on the table, too, just like they were for Ronald Reagan, who raised them eleven times. Because Reagan was a leader. A pragmatist.

And so U.S. Rep. Paul Ryan, R-Wisc. and his cadre, in the face of a $14 trillion budget deficit so dire that the government was nearly shut down last week, that the Environmental Protection Agency and Planned Parenthood were to take debilitating cuts, that a fight over the $14.3 billion debt ceiling makes the world wonder what our problem is, proposes to lessen the tax burden on the wealthiest.

Let’s get this straight. You refuse to even consider raising taxes — even when the numbers show that cutting outlays in meaningful ways will make us more vulnerable and hurt our most vulnerable. It’s fighting the budget battle with one hand tied behind your back. Our problems are too serious to play these games.
