[TheForge] OT propane forge burner book - tarriffs.

[Ralph Sproul]

John,  What the hell happened with Clinton's beloved NAFTA
program..........I thought that was supposed to cut tarriffs between Canada
and Mexico?

        That double the price does not sound like what the North American
Free Trade Agreement is supposed to stand for?  .............or is this
Canada's way of taxing imports to raise revenue for all the subsidized
programs they have?
