If a supplier changes locations I would definitely expect prices to change in future contracts. Of course the current contract shouldn't be changed if we had already agreed on a price for some number of units.

The OEM is selling a tradable, so you would expect companies to already search the world for the cheapest version and be buying that, as there is effectively a single global market.

Labor, historically, has not been so mobile. There is not a single market for labor, there are many different markets.

And in each market, the company pays the prevailing market wage. For that reason, when someone moves from market A to market B, their wages are adjusted up or down based on the cost of labor in those markets.

People pay more for products made in USA than products made in China, even if it is the same product, yes.

I would, yeah. Chances are that the product has changed, same as the now-remote engineer's product

I can't wait for Google to open offices world wide.

Oh wait...

I suspect that the slightly lower confidence in the workforce would outweigh the cost savings, Google has lots of cash.
