Assuming there is "a big shortage in 'high quality' engineers" can anyone provide links to any AWS, Google, Apple, Facebook, SpaceX, position postings which typifies this big shortage? e.g. Postings which are an exemplar, of requiring 'high quality engineers' but remain open for weeks or months due to the massive STEM shortage? Based on the I-squared Act's proposed increase to a 1/4 million (250,000) H1-Bs there should be 10s and 10s of 10,000s such postings.
This massive STEM shortage debate has been happening for years. The referenced article links studies, presents supporting data (aka actual statistics) and provides direct anecdotal evidence (he is involved in the production of STEM resources). Bluntly I have seen many similar fact based articles and studies on the "there is no STEM shortage" side and can't recall a single peer reviewed study on the massive shortage side. Links welcome.
