Globalization is demonized but it's a natural consequence of technology. It's easier than ever to work with production facilities around the world. We can't stop businesses from exploring more efficient production. But we can and should level the playing field. One contributor to the difference in wages for manufacturing employees is the lack of regulations and protections for workers in countries like China. Treaties that support trade are one way to level the playing field. TPP had a bunch of bad stuff in it too, so perhaps not a net win.
