Let's try facts. It is no coincidence that the top eight countries in the "world happiness index" are all incredibly homogenous in terms of their population composition. All eight of these countries have a statistically monolithic racial enthnicity demographic to the extreme. ( Switzerland, Denmark, Iceland, Norway, Canada, Finland, Netherlands, and Sweden ). With the exception of Canada, the birth rates have been relatively static for centuries. This has historically allowed for a viable and sustained wealth redistribution system and generous social benefits in terms of inflows versus expenditures. Natural resource utilization has remained healthy and balanced and the industries, goods, and services for which the citizenry has been employed is in many cases centuries old. Generations of families might be employed in the same fishing or lumber or hospitality livelihood.
In other words, remarkably static monolithic populations where everybody pretty much looks like everybody else and with low, static birth rates and until recently very little immigration (Canada excluded in that remark) and where there is very little competition or segregation in the population.
Canada is slightly an outlier compared to the Nordic countries. In 2006, 89.2% of the Canadian population was Caucasian, 6.7% Asian, and 2.5% Black. The same study identified 66.5% of the United States as Caucasian.
The USA ranks 13th in world happiness report. There is no arguing that the United States is a much more ethnically diverse country than the 12 countries preceding it on the list.
Why do wealthy Canadians move to the US, take up dual citizenships, and winter in the United States ? Why do Canadian graduates frequently take jobs in the United States ?
Canadians want to steal our dance moves, that's why.
