Even so in the parts of Alaska outside of the Arctic Circle there's summers where the sun rises at 3AM and sets at 9PM, then in the winter it's sunrise at 9AM with sunset at 3PM.
In Fairbanks at the winter solstice the sun rises at 10:58 and sets at about 14:40.
At the summer solstice it's 02:57 and 00:47. Even though the sun officially sets year round it never really gets dark between mid April and mid August because the night periods never leave the twilight stage.
That *should* mean there are more males at the bottom end where people really need help
More at the top and more at the bottom, and the effects on earnings are not symmetrical. Once somebody is cognitively deficient enough to be considered a ward of the state the amount of resources they require to survive remains more or less constant with diminishing IQ but on the other end of the curve income potential does not have an corresponding cap.
but there are no such differences in average IQ between males and females
I've seen claims to the contrary stating that there is a small difference in the average and a significant difference in standard deviation.
I watched a guy from Scandinavia doing a interview recently, and talking about these topics. One fact that blew me away was that on average men are overall contributors to the welfare state over their lives, and women, on average, receive 1.3 million (he said dollars - not sure what currency precisely) from the welfare state over their lifetime.
In Scandinavia you see sex-based differences in group averages and in the US those same measurements show both sex-based and race-based differences in group averages.
