This has been the case with several industries (manufacture, service to name a couple) ever since the capital was globalized beginning from late 80's. The difference is that the collusion is a part of some trade agreement (GATT etc.,) where labor movement between nations is severely restricted or banned altogether and capital movement is encouraged in the name of liberalization!

This has resulted in industries being shut down at a massive scale in US where labor costs are higher and moved to a country where labor is cheap (China, India and so on) and also less regulated ("flexible" is the word used). As a bonus companies get to flout just about every environmental regulation which are non-existent in third world countries (think Bangladesh's textile manufacturing plants producing for luxury brands).

The net result of this combination of "free capital movement + restricted labor movement" is reduced wages across nations and industries. And over the time you end up having no skilled labor in a company's nation of incorporation (Apple?).

The supreme irony I see here is that the advocates of "free market" for capital tend to advance amazingly absurd arguments when it comes to having a similar free market for labor.

I highly recommend watching this talk by Noam Chomsky titled "Free Markets?": https://www.youtube.com/watch?v=WHj2GaPuEhY
