”In fact, the nation graduates more than two times as many STEM students each year as find jobs in STEM fields. For the 180,000 or so openings annually, U.S. colleges and universities supply 500,000 graduates.”
This guy quotes completely different numbers :
There are some 40,000 computer science bachelor’s degree earners each year but roughly 4 million job vacancies for computer workers.
NOT "completely different numbers" - and a nonsense comparison. My source compares apples to apples: new STEM workers (grads) to new STEM position. Your source compares a subset of new STEM workers to ALL existing positions.
In all, the median duration of advertising for STEM vacancies is more than twice that of those in other fields.
Which could equally well mean there's a labor oversupply in the other fields. Or that STEM-qualified Americans don't want those jobs at the offered wages - which would mean by basic market economics that wages need to be raised.
Or Americans are not willing to put in the work to get degrees and education, or move to where those jobs are.
I can see it here, its the immigrants with two parent families making their kids study and go to college, the American boys want a great job selling cars and the teenage girls are interested in having babies while living at home.(heck, dad;s long gone and they live with mom)
If ya 4 million job vacancies for computer workers and big unemployment in other fields than simply raising salaries will do nothing.
