The money flow matters. It matters because those are jobs that Americans aren't getting. That friend of yours in the US that down on their luck and looking for a job? That's a job they could be doing. The Everyone driving for Uber could be doing it from their living room in the US. The money that Waymo riders are spending is going to other countries, not America. I'd pay more for an all American company who had remote drivers in the US.
The US intentionally keeps its unemployment at the current rate to keep labor costs down. If your friend can't get general skills jobs it means the average job in the US will pay more and the total of all pay in the US will be more.
I think the US should stop being so abusive and mean given how damn rich it is.
