Spending ~$100M on employee housing would make the compensation a lot more competitive since software salaries are high but tend to be located in HCOL areas. Spend another ~$100M on training and education facilities and I think you could attract a lot of Americans right of of high school. Even if it still a bit less competitive than software it could still be the second best career industry.
I think the industry already partly does this but doing it on a larger scale and marketing it as an alternative to college would make it more compelling. I think the industry is still like many other large industries that really want a degree in some engineering despite it not necessarily being very applicable to fab work.
