美国工作多, 而且工资高, 人更加open. 基本公式如下:
1. 工资30K/year但是小于70K, 加拿大和美国持平, 各有胜负
3. 工资>70K/year, 美国胜出.
由于绝大部分人的工资在30K至70K之间, 所以加拿大人和美国人在各自的国家过日子. 不过加拿大人才喜欢去美国(参见3). 下面是英语, 喜欢进一步研究的可以看一下.
According to a report by Statistics Canada about 167,300 Canadian residents moved to the U.S. between 2001 and 2006*. That’s about 33,000 per year. By comparison about 9,000 Americans move to Canada each year, and the U.S. has nine times as many people. (And, by the way, only about 1000 more Americans moved to Canada the year after George W. Bush was reelected.)
*Update, June 29th, 2012: The Statistics Canada report provides data from both the Canadian census' Reverse Record Check (RRC)—the data cited in the piece—and the American Community Survey (ACS). The American Community Survey estimates that, in 2006, 73,000 people residing in the United States lived in Canada one year earlier; 34,000 of those people were born in Canada. Do emigrants from Canada to the U.S. stay in the U.S.? For 2006 the RRC data suggests that "approximately one-third of emigrants from Canada to the United States intended to return to Canada".
