Y'all can't be this dense. 

Tariff's don't "Bring revenue to China." They're a tax. They're a cost to the producer. The U.S. doesn't pay them, Chinese companies do. Same thing here in the U.S. "China" doesn't pay the tariff's, U.S. companies and consumers do, so they're just another tax on consumers, they're not some kind of "free" money. 

The Obama administration had negotiated the TPP, which, gasp, dropped almost all tariff's and trade barriers among member nations. So, yes, you pass on the TPP, but you also pass on preferential trade with the entire Pacific Rim? That's stupid. Sorry. 

And, yes, Brazilian farmers face all kinds of problems, including their currency. And? You think a weakening of the Real is good for Brazilian farmers?
