work ethic in the US parallels that of Europe -- high in high latitudes, low in low

sociologists have noted this also, and attributed it to either heat or seasonality (in cold areas you better get your work done in summer and fall or you will not survive the winter)

but! there was heavy migration from Europe to the US so that might explain things here

real tests would be to look at Asia and S. America to see if those in colder areas are similar
