How do you know what TPP will do if TPP is still under negotiation?
No law can be changed through a trade agreement unless made by Congress. A foreign government or foreign body cannot make, change or amend US law. Only the US Congress can do that.
Moreover, the publicly available TPA bill states that no trade agreement can alter US law.
With TPA, you like everyone else will have 60 days to review the proposed trade agreement before Congress can take any action on it.
It is foolish to suggest you know the content of TPP or any other proposed agreement without having to actually review it yourself (during that 60 day window granted by TPA)
The very fact that it is under secrecy to our representatives tells me all I need to know. This is Obamacare redux in re trade.
Why are you so willing to TRUST the overlords?
