Of course not. Any company that doesn't use the cheapest method of production that it can is going to be out of business very soon.
In countries where labor is cheap, goods will be produced by humans; in countries where labor is expensive, goods will be produced by machines.
The trade-off is whether to use machines in the US or workers in Mexico. There never will be high paid workers in the US doing these jobs.
I think there is a lot of benefit by helping the Mexican economy and letting their people do these jobs.
