What is the Keynesian view of the role of government vis-a-vis the free market?

0:00And so the Keynesian picture of the economy is essentially one where a free market economy is essentially one where the economy is like an automobile and you're driving down a very narrow sort of tightrope or ledge with two abysses on either side. One is the abyss of unemployment, which occurs if there's too little spending. The other is the abyss of inflation, which occurs if there's too much spending. And the task of the government, the government is sort of the pop-up driver of the car, obviously if you have an economy in the car you have to have somebody driving it. And so the task of big brother government is to be at the steering wheel, keeping, fine-tuning the economy in such a way as to keep total spending perfectly, precisely attuned to the so-called full employment line, which is that the economy doesn't fall off on one hand of the abyss of depression and the other hand of the abyss of inflation.
