Shortage of US STEM workers?

"Among the 50 million employed college graduates ages 25 to 64 in 2019, 37% reported a bachelor’s degree in science or engineering but only 14% worked in a STEM occupation, according to the Census Bureau’s 2019 American Community Survey 1-year estimates.

This translates into less than a third (28%) of STEM-educated workers actually working in a STEM job." This explains why the STEM corporations (like MUSK) lie about a shortage....foreign STEP employees cost less to employ and are easy to control, with longer hours, etc. In fact, the US is full of STEM graduates serving coffee at Starbucks, while foreign visa holders take their jobs for a lower wage. The reason: maximize profits by lowering wages. Meanwhile, H-b2 workers who roof our homes and harvest our food and for whom there is a genuine shortage are threatened with deportation, which would raise the price of housing and food and leave crops rotting in the field ,as the wages to attract US workers would have to rise to a level that would make US crops uncompetitive...and so Trump could tariff Mexican and Chinese food imports, which would create more bankruptcy for US farmers (hit by retaliatory tariffs, as China did) who then would be bailed out by the government (Trump put them on welfare, with 25 billion for NOT growing crops they could not sell), which could be paid by the sales tax of tariffs imposed by Trump, leading to 1. loss of jobs 2. inflation 3. more government welfare for industries crushed by retaliatory tariffs.
