It should be “A person’s pay”, but a lot of tech offices are in high cost of living places like the Bay Area. If you don’t have to show up in San Jose consistently, you can hire from wherever and most other places will have a lower cost of living.

So someone in Austin may be willing and able to do the same job as someone from San Jose for 20% cheaper because their lower cost of living still makes it work it. Or maybe someone in Monterrey, Nuevo Leon may be willing and able to do the same job for 60% cheaper.

Suddenly, those high salary tech positions go away because major tech companies are no longer limited on where they can source talent.
