I remember when darker brown people were considered to have a lot of "stamina" in the US. Now we've changed our focus to a lighter shade of brown I guess. Progress?
My memory of construction sites in urban Texas about 15 years ago, was that the day laborers I worked with were very nearly all African-American, and it was the skilled workers constructing the high rises who were Spanish speaking. No idea if that was representative or just the neighborhood or if it is different these days. I imagine that there is more grueling work though than cleaning up rebar and junk so I don't know what it says about stamina.
