> According to this Joint Venture Silicon Valley report, 74% of Silicon Valley tech workers are foreign-born immigrants. A decade ago, 36% of Silicon Valley tech workers were born abroad. In 2000, only 29% were.

> Tech industry employment has increased from about 300,000 jobs in 2007 to 400,000 in 2016, so even though we created 100,000 engineering positions in the last decade, we’ve also displaced 88,000 domestic engineers.[1]

> American tech workers are getting pushed out, and they aren’t coming back

If the downward pressure on salary in American software jobs is so extreme that salaries frequently go all the way to zero, while there is a countervailing upward pressure on salary among Indian no-job-yets, why do we say it's "categorically false" that there is a downward pressure on American software salaries?

[1] Note that this is what you expect from a pricing shift, not an increase in the value created by the work. The quantity of software labor purchased has gone up and sellers are being forced out. If the driver of increased quantity-of-jobs were increased value created, you would see sellers entering the market, not leaving.
