Perhaps, but I could take these arguments more seriously if western countries weren't so excited about issuing more visas for tech workers. It's also possible that we have a tech bubble that people are wisely avoiding.
For that to make sense you'd really have to believe that the US will need fewer, not more, STEM jobs in the future. The vast majority of educated STEM workers and engineers are completely removed from venture-funded Silicon Valley startups and any potential 'tech bubble.'
The goal is gender balance, there's no need to fear that a woman or a person of color accepting a newly created STEM job will somehow push a white man out of his existing position. Let's be realistic here.
