Maybe not old enough for this question to matter, but I'll ask it anyway, alberta liberal: how did you feel about 50,000 American "draft-dodgers" coming into Canada in the late 60s to mid-1970s?  Because they were "healthy", and "young" and literate and fairly well educated (by world's standards, at least) I'd say they were a bargain. 

Point 2: don't use your own terms of reference or situation to judge "so many from other parts of the globe."  It's a different world out there, alberta...
