Mainstream Economics is not a practiced as a science of cooperation man but as a science of the deception of man. Not how to improve cooperation by reducing transaction costs and uncertainties but how to force consumption for the purpose of increasing employment.
Of course the simplest method of achieving the same result is to stop distorting the labor economy and directly redistribute liquidity to consumers such that employment makes less of an impact on the unemployed.
That would also have the side effect of impoverishing the financial sector. Which is a good thing.
