What we call 'Free Trade' is more accurately called 'labor arbitrage'.
In other words, a race to the bottom via workers wages. Now just who had the lowest labor costs in the years leading up to WWII?
If you guess Japan and Nazi Germany - you win the Kewpie Doll. It was bad enough that the Western Democracies allowed Hitler to take the Cechkosovakian* arms works without a shot ... imagine how much more wealthy the Jerries would have been if they had enjoyed a free access to the American Market?
Most free traders on this forum state they were too smart to get drafted - so they really don't appreciate just how much the GI wants his opponent to be ill fed - and lacking supplies....
Some things you just cannot place a dollar value on.

Should've put a < sarc> < /sarc> tag on that. I did not mean to go there in earnest. While it may be true, it is an indefensible argument; just like the one made by the article poster. You can't prove causality in these cases without tons of PhD level work.
