But I also think it's totally wrong to say we don't have a technology labor shortage. The best evidence of this are the salary numbers for people with math and science degrees. It's not because physics and math suddenly got more valuable. It's because tech is so starved for labor it's hiring people from different disciplines to do the job and it's actually brought the average salaries in line with CS and engineering graduates.
Also, even if we had an adequate national labor supply, the job opportunities are not distributed proportional to population density. The density of technology jobs is highly concentrated in a few parts of the country, but we are producing qualified engineers everywhere. And not everyone is willing or able to move.
