Funny.... I could have sworn that I've read this same thing from Canadians over and over again.... particularly about our hockey teams
Anyway, Canadian companies have been high tailing it out of Canada for a long time... mostly back when the $$ was at a point where it was cheaper for Canadians to go shop in the US.
Then it reversed to where it was cheaper for the US to shop here.... in which case, it also became cheaper for the US to hire Canadians to do a majority of things, like phone and data centres.
I think the major difference is that Canada never lost sight of what our key strengths were.... lumber, fish, minerals... you know, our major resources.
The US... well.. what's left to really claim as their own, or to consider as a "key export"?
The US wasn't losing money until Dubya stepped in... and he certainly wasn't the start of the "deconstructing" of the USA... so... really, money will still coming in strong and fast for the US even as the jobs and specialists and what not were leaving.
So, is it really such a bad thing?
