True, the federal government has avoided all-out austerity. But state and local governments, which must run more or less balanced budgets, have slashed spending and employment as federal aid runs out — and this has been a major drag on the overall economy. Without those spending cuts, we might already have been on the road to self-sustaining growth; as it is, recovery still hangs in the balance.
The infuriating thing about this tragedy is that it was completely unnecessary. Half a century ago, any economist — or for that matter any undergraduate who had read Paul Samuelson’s textbook “Economics” — could have told you that austerity in the face of depression was a very bad idea. But policy makers, pundits and, I’m sorry to say, many economists decided, largely for political reasons, to forget what they used to know. And millions of workers are paying the price for their willful amnesia.
