A bit of a rant here in this item . Unfortunately it is never a plan but the natural result of ill considered decisions never been corrected.. A collapsing economy will generate a true revolution as the desperate hit the bricks. Our present global problem is that the now universal global expansion has been seriously unbalanced and difficult to deal with in historically high wage earning countries. That was inevitable but could have been ameliorated better.
The best solution for tariff elimination is to establish a treaty that is enacted ten percent per year for ten years. It allows time for all actors to make changes to survive. It worked very well when it was applied in NAFTA. Not so well when the Chinese discounted even the low wages in Mexico without meaningful treaty arrangements.
The real solution is the ending of poverty using my methods discussed elsewhere.
