> The TPP had serious flaws and I am glad it was never passed. It was far too secretive, with the most powerful existing interests dictating policy and regular citizens being completely cut of of even viewing what was in the actual agreement for far too long, until the thing was nearly finished.
You mean like almost every treaty ever negotiated pretty much as far back as we have recorded history?
A treaty negotiation is a give and take. Each side goes in wanting to gain certain things, and being willing to concede certain things to get those things it wants. The purpose of the negotiation is to find a set of gains and concessions for each party such that the party will agree to the treaty for those gains at the cost of those concessions.
During negotiation, what is on the table changes as each party gives up on certain wants, or accepts certain concessions, to further its overall goals.
It would be nearly impossible to do this in public. Every time you go from draft N to draft N+1, anyone who had gains in N that are no longer in N+1, or who is part of concessions in N+1 but not in N, would be putting political pressure on the negotiators to go back. Everyone who got gains in N+1 that weren't in N, or had concessions in N but not in N+1, would be putting political pressure on negotiators to not cave to the pressure to revert.
The only known way to make it work is for each party to send negotiators who know that party's big picture goals, work out a near final draft, and then present that more widely for a yes/no decision on ratification.
