I think you are overestimating the size of the eligible labor supply increase. Just for Google, for 2017-2019 the number of H1B workers sponsored was 22k. For the same period the increase in number of full time employees was 40k (couldn’t find the figure for US only but fair to assume majority is US-based). So more than half of the new employers are supplied internationally. Does the geo-unlocked US supply pose a sub…
I'm curious - you seem to be saying that FAANG companies can't find enough employees, but your support for the point is that Google hired a significant amount of H1B workers. However, I've read/seen that many H1B workers work for significantly less, and under more pressure, because they are trying to become citizens in the US. Is it possible that the reason for FAANG companies hiring so many H1B workers isn't due to…
For your second point, the delta of the “higher salary” is important. US ranks the highest in sofware engineer salaries globally, which means for most countries coming to US as a software engineer will mean a much higher increase in salary than within US. If that delta offsets the perceived cost of leaving friends and family behind, they it is rational to take the offer. In other words, non-US candidates need to be hurting much more than US candidates to lose access to friends and family to not take the offer. In fact they already do, they lose access to their culture and their language unless they are from anglosphere. They still take the offers, so the income differential must be more than adequate to make the transition. Additionally, individual cost function of losing access to these things will differ. Many people will actively seek a challenge away from their friends and families to take up new opportunities and experiences. Your friends seems to have not.
