There are many such examples where economics no longer speaks to the real world.
Two other examples will suffice:
Most intelligent people are aware that natural resources are finite, including the environment’s ability to absorb the wastes or pollution from productive activities (see for example, Jared Diamond, Collapse, 2005). But few economists are aware, because economists assume that man-made capital is a perfect substitute for nature’s capital. This assumption implies that there are no finite environmental limits to infinite economic growth. Lost in such a make-believe world, economists neglect the full cost of production and cannot tell if the value of the increases in GDP are greater or less than the full cost of producing it.
Economists have almost universally confused jobs offshoring with free trade. Economists have even managed to produce “studies” purporting to show that a domestic economy is benefitted by being turned into the GDP of some other country. Economists have managed to make this statement even while its absurdity is obvious to what remains of the US manufacturing, industrial, and professional skilled (software engineers, for example) workforce and to the cities and states whose tax bases have been devastated by the movement offshore of US jobs.
The few economists who have the intelligence to recognize that jobs offshoring is the antithesis of free trade are dismissed as “protectionists.” Economists are so dogmatic about free trade that they have even constructed a folk myth that the rise of the US economy was based on free trade. As Michael Hudson, an economist able to think outside the box has proven, there is not a scrap of evidence in behalf of this folk myth (see America’s Protectionist Takeoff 1815-1914).
