demand-side has been debunked again and again, but it continues. Why?
Because it enables those in power to distribute huge sums of money to their power group. In the final result, they don’t mind getting kicked out of power, because in the meantime, they have been enormously enriched by having had access to the government checkbook.
It also sets up a possible revolution in which they can re-initiate an aristocracy....otherwise known as “a dictatorship of the proletariat.”
Demand side economics in a democracy is nothing less than Bribe-Side economics. You take money from people who don’t vote for you and give it to people who do vote for you. Eventually you buy yourself permanent power.
