And the opposite is true. Every time a new trade deal reduces or eliminates tariffs on goods imported into the US, that increases the incentive for US transnationals to move production to some cheap labor nation.
That's been a primary goal of many trade agreements: eliminate tariffs and make relocating US plants to cheap labor nations even more profitable because the goods they ship to the US will be tariff free.
And TPP will only continue and accelerate that practice. The usual BS about opening foreign markets for US products and creating jobs in the US is just that, BS. Agriculture and a few industries benefit from some trade deals, but that's about it. The deals always increase the incentives for US manufacturing to be relocated to cheap labor nations.
You and I get it. It is so simple but so hard a concept for some to grasp. What is their problem? Are they just stupid?
