Indeed, the devil can be found in the fine details. The lawyers and the accountants will be the death of us yet.
However, perhaps we'll fare better than the doom and gloom being forecast and reported by isolationists.
I think one has to be careful what they consider an isolationist to be. Were we isolationists prior to 1990? Because prior to 1990 we did not pursue the trade policies we have adopted since then. We had never signed an agreement like NAFTA before that. We did not allow about one million illegal immigrants to cross our borders either.
Our founding fathers would never have signed trade agreements which saw 40% tariffs placed on our exports, but zero tariffs placed on items we purchase from other nations.
