"Free trade" will never be viable unless it also fair. For it to be fair it must be governed by a common set of rules and regulations (aka "World Government").
With World Government come all the disadvantages associated wtih any monopoly.
That's reality.
Which brings us back to NAFTA, GATT, etc.
Are you saying there should be NO NAFTA, etc.? Or that the rules are unfair to the US?
I recall 'fair' as a warm and fuzzy word Liberals like Walter Mondale used to use a lot. Like "fair taxation" (meaning: tax the rich), or a 'fair wage' (meaning: give in to the unionist demands), etc.
What is "fair"? Isn't it "fair" to allow willing sellers and buyers to go about their business without the Government making it illegal?
