Now, couple this with the ease at which Canadian engineers can get jobs in the US and the picture emerges, bright and clear. Any Canadian with a lot of ambition may be alienated by the relaxed culture in Canada and subsequently move to the US, further reinforcing the cultural divide.
On the other hand, Canadians (and even Americans) who are disillusioned with what they may see as an excessive ambition and a relentless focus on "growth hacking" might opt to live in Canada, also reinforcing the cultural divide.
