Recently, the Economic Policy Institute issued a report claiming that there is no shortage of U.S. STEM workers and that increases in high-skill immigration are not needed and detrimental to the U.S. economy. In this report, ITIF presents a detailed rebuttal of the EPI analysis to provide a more accurate picture of the high skill labor market. We find that the EPI report's conclusions are simply not supported by the evidence. In fact, the U.S. does not produce enough STEM workers domestically, STEM wages and jobs have grown significantly over the last decade, and high-skill guestworkers are a complement, not a substitute, to American high-skill labor.
