Nonsense. Should I post the graphs again? The graphs clearly demonstrate increased production without a corresponding increase in employment. This is the "jobless recovery" that many columnists lament. Some graphs again:
According to Keynesians (e.g. Krugman), recessions are caused by labor not becoming cheap in response to exogenous shocks (due to sticky nominal wages). Do you disagree with this theory?
If fishes rode bicycles... but they don't.
Productivity growth doesn't change that much year over year:

And recessions are generally times of low change, since it doesn't make sense to invest in labor-saving technology when labor is cheap.
> production need not be correlated with employment.
In a speculative robot-filled future, that could be true. On Earth in 2012, if you want something done, you hire a human to do it.
