Although educational credential inflation expands on false premises—the ideology that more education will produce more equality of opportunity, more high-tech economic performance, and more good jobs—it does provide some degree of solution to technological displacement of the middle class. Educational credential inflation helps absorb surplus labor by keeping more people out of the labor force; and if students receive a financial subsidy, either directly or in the form of low-cost (and ultimately unrepaid) loans, it acts as hidden transfer payments. In places where the welfare state is ideologically unpopular, the mythology of education supports a hidden welfare state. Add the millions of teachers in elementary, secondary, and higher education, and their administrative staffs, and the hidden Keynesianism of educational inflation may be said to virtually keep the capitalist economy afloat.
As long as the educational system can be somehow financed, it operates as hidden Keynesianism: a hidden form of transfer payments and pump-priming, the equivalent of New Deal make-work setting the unemployed to painting murals in post offices or planting trees in conservation camps, Educational expansion is virtually the only legitimately accepted form of Keynesian economic policy, because it is not overtly recognized as such. It expands under the banner of high technology and meritocracy—it is the technology that requires a more educated labor force. In a roundabout sense this is true: it is the technological displacement of labor that makes school a place of refuge from the shrinking job pool, although no one wants to recognize the fact. No matter—as long as the number of those displaced is shunted into an equal number of those expanding the population of students, the system will survive.
