Doesn’t matter if they want to leave or not. It’s still cheaper for them to produce in China than it is in the US. Even with the tarrifs and wage increases. And these soulless, lifeless mega US multinationals care about nothing more than the bottom line period. The people running them have sold out their own country all in the name of the almighty dollar.
And my point is that when those jobs move out of China, they're not moving to the US. They're moving to other LCCs.
A lot of the remaining LCCs are Southeast Asia. We haven't yet tried to exploit Africa yet... But wait.
And as
@utee94 points out, as long as we make pricing decisions based on $, that's what corporations are going to do.
We've gotten to the point, comparison shopping, that even our "premium" airlines like American, United, Delta, etc are charging to actually select a seat. Because once you have the internet and can look at prices head-to-head, typical travelers will sit outside the airplane on the wing if it saves $3. (Of course, then they'll bitch about the wind noise--because 'Murica.)
