I’ve worked with awful, stereotypically garbage offshore teams. I’ve worked with quality offshore teams. The difference was money. The quality teams made less than, but nearly as much as an American worker. Maybe not a FAANG guy or a New York / SF worker, but all those small cities in flyover states? They came in 20-30k under, perhaps.

Language l, cultural, and time barriers still come into play regardless of how good they are, however.
