Mainstream macroeconomics has always had problems with the notion of involuntary unemployment.

In New Classical Economics unemployment is seen as a kind of leisure that workers optimally select. In the basic DSGE models used by these economists, the labour market is always cleared – responding to a changing interest rate, expected lifetime incomes, or real wages, the representative agent maximizes the utility function by varying her labour supply, money holding and consumption over time. Most importantly – if the real wage somehow deviates from its “equilibrium value,” the representative agent adjust her labour supply, so that when the real wage is higher than its “equilibrium value,” labour supply is increased, and when the real wage is below its “equilibrium value,” labour supply is decreased.
In this model world, unemployment is always an optimal choice to changes in the labour market conditions. Hence, unemployment is totally voluntary. To be unemployed is something one optimally chooses to be.
Yours truly has to admit of being totally unimpressed by this kind of New Classical macroeconomic quackery. I guess Keynes would have felt the same:
The Conservative belief that there is some law of nature which prevents men from being employed, that it is “rash” to employ men, and that it is financially ‘sound’ to maintain a tenth of the population in idleness for an indefinite period, is crazily improbable – the sort of thing which no man could believe who had not had his head fuddled with nonsense for years and years …
Our main task, therefore, will be to confirm the reader’s instinct that what seems sensible is sensible, and what seems nonsense is nonsense. We shall try to show him that the conclusion, that if new forms of employment are offered more men will be employed, is as obvious as it sounds and contains no hidden snags; that to set unemployed men to work on useful tasks does what it appears to do, namely, increases the national wealth; and that the notion, that we shall, for intricate reasons, ruin ourselves financially if we use this means to increase our well-being, is what it looks like – a bogy.
John Maynard Keynes (1929)
