As an example in another part of the world, look at the ethic Chinese in Indonesia. Disproportunately successful. Of a different religion than the majority Muslims. Of a culture that valued education and hard work. Kept themselves separate. They were disproportionately slaughtered in 1965 (The Year of Living Dangerously) and subjected to pogroms other times
Jews are hated because we make better bagels than anyone else.
(That's the REAL reason no one wants to admit.)
Thanks for reminding me of the ethnic Chinese in Indonesia example. You are so right; Thomas Sowell also uses it in one of his books about ethnicity and economics.
