Trump is right, we are exporting our jobs because of poor tax policy and excess regulation.
Trump may also be right about “free” trade agreements depending how they are negotiated. The TPP is thousands of pages long and was done in secrecy. Much of it was negotiated before the Obama Tyranny. Obama has not done much in the interest of the USA, and don't make me list his record. OK fine, three huge examples: ObamaCare, the Iran Trade Nuclear Deal and the Taliban Exchange.
Now a huge a aside, Expat. This caught my attention yesterday except experts say it is now $9 Trillion instead of $7 Trillion (link only, hopefully that is alright):
My comment, WTheck! This cannot be good!
Wait a sec., if it's done in secrecy how do you know how many pages are in it?
