Agreed that it would be gone if it was feasible. I worked for a small manufacturer and helped with quoting. It was three times less for us to send a product to Mexico for production.

Where the US is better is automation and complexity. In Mexico or was difficult to find the technical resources able to handle automated and complex projects. Mexico was better for any manually/ sinple assembly job, as they could just throw more people at it to ramp up production. Note that these are generalities that my specific team used.
