Not true at all, labour costs only make few percents of high value goods you import from third world countries.

Even if they were to go up tenfold, it will not make that much of difference.

People who moan about labour costs making any difference to modern manufacturing are just keeping regurgitating a myth.

In fact, trained manufacturing labour costs in coastal China are now significantly passing that of US averages, and even more so of US flyover states.
