The Keynesian argument that the government sometimes need to prime the pump has been widely discredited. However, liberals and progressives cling to their faith that the government must spend to stimulate the economy.
I say “faith” because it is a concept that is accepted without proof. In fact, accepted in spite of all the evidence to the contrary.
