Reports by the Economic Policy Institute (EPI), the RAND Corporation, the Urban Institute, and the National Research Council have all found no evidence that STEM workers are in short supply. PBS even published an opinion piece based on the EPI study entitled, The Bogus High-Tech Worker Shortage: How Guest Workers Lower U.S. Wages. This is PBS, mind you, which is as likely to publish something skeptical of immigration as it is to publish something skeptical of taxpayer subsidies for the Corporation for Public Broadcasting.
