Mainstream economics is hopelessly adhering to a big lie. There is absolutely no chance that monetary policy or fiscal policy will ever benefit society as a whole. Yet the world is still captivated by the notion that either of these theories are necessary for enhancing the economy. Growth is attributed to both.
The fact is that human nature prevents both modern monetary theory or fiscal policy from working as intended. There is no question that each has an influence over the economy. But, that influence can never be anything in the name of public good or even results that are expected.
I wonder, if the multitude of economists whom adhere to these concept believe that objectivity in using them is completely unnecessary. Is it fine that the economy is just stimulated just for the heck of it or randomly?
Ask your economics professor, or your favorite economist how it is determined that economic intervention is necessary and called for? An economic decision is made by a child with $5 to spend in a candy store. He is careful to get as much candy that he likes as can possibly be obtained for $5.00.
Do governments make economic decisions? No, it is impossible. Governments make political decisions. So, even if intervention had a chance of working, the fact that governments can ‘t make economic decisions guarantees a miserable outcome for society at large.
So what are modern monetary and fiscal policies good for? They are extraordinary political tools.
