SHOULD the government cut spending or raise taxes to deal with its long-term fiscal imbalance? As President Obama’s deficit commission rolls out its final report in the coming weeks, this issue will most likely divide the political right and left. But, in many ways, the question is the wrong one. The distinction between spending and taxation is often murky and sometimes meaningless.

Imagine that there is some activity  say, snipe hunting  that members of Congress want to encourage. Senator Porkbelly proposes a government subsidy. “America needs more snipe hunters,” he says. “I propose that every time an American bags a snipe, the federal government should pay him or her $100.”

“No, no,” says Congressman Blowhard. “The Porkbelly plan would increase the size of an already bloated government. Let’s instead reduce the burden of taxation. I propose that every time an American tracks down a snipe, the hunter should get a $100 credit to reduce his or her tax liabilities.”

To be sure, government accountants may treat the Porkbelly and Blowhard plans differently. They would likely deem the subsidy to be a spending increase and the credit to be a tax cut. Moreover, the rhetoric of the two politicians about spending and taxes may appeal to different political bases.
