Economics tells us that it's impossible for computer A.I. and automation to take all of our jobs. The reason is that the corporations that are investing and implementing automation technology would be shooting themselves in the foot because human employees are also the very customers that buy their goods and services. Eliminate the jobs and you eliminate the very customers you need to survive. Economics tells us that if the demand for something goes to zero, the supply will also go to zero.
Supply-side economics is the heart-beat of Republicans economic agenda as the Trump Administration aims fiscal policy squarely at shifting the supply curve outward and undoing the disastrous years of stagnation during the Obama Administration which resulted in the supply curve shifting inward.
