The free market certainly does NOT kill U.S. sovereignty. How can people get so confused?
Sovereignty has to do with enforcing U.S. political and constitutional law, not with the voluntary cooperation of the market economy which, if run right in terms of foreign trade, would have minimal government interference.
TPP kills sovereignty by allowing our country to be over run by foreign workers. Jeff Sessions has sounded the alarm on this and other sovereignty issues that TPP raises.
TPP is not free market. It mandates conditions for contracts and who you can trade with.
