TJ, Yes. IMHO, The best is what the U.S. of A. Constitution requires between the states of the union. No tariffs allowed. But, Our Constitution uses less than two paragraphs to accomplish that. THAT is free trade, as well as fair trade. The politically appointed bureaucrats making today's "free" trade authors use thousands and thousands of pages of rules and regulations given the color and force {that's guns} of law WITHOUT LEGITIMACY to CONTROL trade with and between godgov's favored nations and select {licensed} traders. NOTHING is free in these "free" trade agreements, made up by politically appointed bureaucrats, that they want to give {Actually withold until after the vote} to Congress for an up or down vote. In other words, these agreements must not be able to stand the light of day even among those who make up "the best government money can buy". NO FAST TRACK!!!! Peace and love, George.
We pretty much agree on that, but the constitution gives the government the right to charge tariffs in order to raise the money needed to operate the federal government. I would favor a return to only the constitutional powers of the government which could easily be funded by a small, consistent (same for all parties) tariff which would enable us to eliminate the income tax. (which the founders specifically forbade)
Just my opinion.
