As the debate over President Obama’s economic stimulus plan gets under way, one thing is certain: many of the plan’s opponents aren’t arguing in good faith. Conservatives really, really don’t want to see a second New Deal, and they certainly don’t want to see government activism vindicated. So they are reaching for any stick they can find with which to beat proposals for increased government spending.

Some of these arguments are obvious cheap shots. John Boehner, the House minority leader, has already made headlines with one such shot: looking at an $825 billion plan to rebuild infrastructure, sustain essential services and more, he derided a minor provision that would expand Medicaid family-planning services  and called it a plan to “spend hundreds of millions of dollars on contraceptives.”

But the obvious cheap shots don’t pose as much danger to the Obama administration’s efforts to get a plan through as arguments and assertions that are equally fraudulent but can seem superficially plausible to those who don’t know their way around economic concepts and numbers. So as a public service, let me try to debunk some of the major antistimulus arguments that have already surfaced. Any time you hear someone reciting one of these arguments, write him or her off as a dishonest flack.

First, there’s the bogus talking point that the Obama plan will cost $275,000 per job created. Why is it bogus? Because it involves taking the cost of a plan that will extend over several years, creating millions of jobs each year, and dividing it by the jobs created in just one of those years.
