>>5There might be positives for the States should Canada join them, but there wouldn't be any for Canada. Not trying to be offensive, but Canadians don't really like Americans all that much, and our values are way different.
As for America being 'the best country in the world', that is your opinion and many people would disagree with you. No free health care, rampant racism, and the highest prison population in the world? That's not really my idea of the best country...
But I can see why you guys would want to join Canada ;)
