The economists who were screaming about the worst recession since the 30's had a vested interest in pushing the economic stimulus plan.
In historical review though, the recession wasn't caused by business overinvestment and the resulting pullback, but by a massive liquidity crunch across the world's financial players. Once the finance sector stabilized, the economic growth (GDP, jobs & wages) should have rebounded much faster. But it didn't, because domestic profits were made from cost reductions, lower interest rates, tax depreciation gimmickry and stashing profits overseas.
