All credible research finds the same evidence about the STEM workforce: ample supply, stagnant wages and, by industry accounts, thousands of applicants for any advertised job.
The real concern should be about the dim employment prospects for our best STEM graduates: The National Institutes of Health, for example, has developed a program to help new biomedical Ph.D.s find alternative careers in the face of “unattractive” job prospects in the field.
Opportunities for engineers vary by the field and economic cycle – as oil exploration has increased, so has demand (and salaries) for petroleum engineers, resulting in a near tripling of petroleum engineering graduates. In contrast, average wages in the IT industry are the same as those that prevailed when Bill Clinton was president despite industry cries of a “shortage.” Overall, U.S. colleges produce twice the number of STEM graduates annually as find jobs in those fields.
In the face of these stark facts, we now see several studies that seem to be desperate Hail Mary passes, using rather unconventional means to find “shortages.”
