There is truth to this, certainly. In software engineering or related positions? I don’t think so, generally. If this was the case we wouldn’t also outsource positions.

Invert your argument: If outsourcing was so great, we wouldn't have any software jobs in the US.

The reason to outsource, to offshore are far more nuanced than "cost".

That’s not the inverse though. I didn’t claim outsourcing was bad.
