Kind of proves the notion that Blacks and Hispanics rank much lower on the IQ and common sense scale.
Seems I recall a recent study by the Heritage Foundation (I *think*) indicating the vast majority of people from south of the Rio have very low IQ scores for generations.. Generations!!
so might a study of what has become of the old British Empire....based on who rules it now.
Actually, it proves that individual "can-do" ruggedness improves outcomes; that dependency, group-think and wealth distribution diminishes (across the board) outcomes.
