David Friedman raises a very good point:
A well chosen name wins an argument by assuming its conclusion. Label cash subsidies to foreign government as "foreign aid" and who can be so hard hearted as to oppose them? Call subsidies to the public schools "aid to education" and you neatly skip over the question of whether additional spending in the public school system results in more education.
And "economic stimulus" is a classic example.
Everyone—including Obama, back when he was running for President—is against deficit spending. Relabel it "stimulus" and everyone is for it. The label neatly evades the question of whether having the government borrow money and spend it is actually a way of getting out of a recession—a claim for which evidence is distinctly thin. It is stimulus, so obviously it must stimulate.
So what should we call it? President Obama's spending proposal? The deficit-spending package? I think we'd have trouble getting the media to call it the Big Boondoggle. Maybe the government bailout, following the Wall Street bailout and the auto bailout?
Alas, we're probably stuck debating the "stimulus." But that means the battle was half lost before it began.
