For the record the Open Skies agreement which is what sets the stage allowing this is a George HW Bush program. But both parties are guilty of cutting bad trade deals for the American worker. NAFTA, TPP, CAFTA, PNTR etc. No real policy change over the last 2 decades. I wonder if the billions of dollars they get from Wall Street has anything to do with it? Nah.
If you want to stop it at the polling booth, there is literally only candidate consistently taking a stand against outsourcing jobs via free trade agreements and that's Bernie. But he'll raise your taxes, and prices of rollaboards at Costco will go up if he adds tariffs; so, Trump maybe, who knows what he believes. He'll make it better though, he guarantees it! Nobody does free trade and/or protectionism better than him and divides/unifies better than him, just trust him. He'll make jobs appear via magic force of personality while cutting your taxes and making everything great.
Otherwise the best place to fight this is with *strong organized lobbying*. Such as ALPA is doing. But, of course, ALPA dues are too much and in-house unions are cheaper so... write you congressman I guess? That'll make you feel like you're doing something at no cost to you.
