And who would chose how much and to whom? The Secretary of the Treasury?
The US Treasury simply sells T-notes to banks, and banks make the funds available. If there is no Demand for those funds, they do not seep into the economy and do not help. Which is exactly what happened post-GreatRecession.
The Replicants in the HofR refused adamantly any further stimulus-spending from 2010 onwards in order to thwart Obama's reelection. That failed, of course. But, neither did the economy create any net new-jobs from 2010 to 2014 because there was no stimulus-spending to do so!
I think Europe has proven that governments should do "the least possible" to interfere in a market-economy. Because by doing so, they screw it up the most.
Getting into economic Deep-Sneakers is a lot easier than getting out. (Every recession proves this point - and yet we remain blind to the fact when it comes to economic governance.) But governments should also do the most possible to assure that those who suffer most are NOT 14% of the population.
And I am am convinced that to do so would reduce crime-rates
magnificently in the US! Where there is a great need to do so!
