Father Greely, the liberal priest and sociologist.published a work comparing the financial achievements of different religious groups. Apparently, being a member of a particular religious group has a bearing on achievement. Jews were at the top, followed by Irish Catholics, Polish and other ethnics were further down, as were some protestant groups. Sowell has written a book called “ Black Rednecks.” arguing that northern blacks who move north have adopted the anti-intellectualism long associated with southern poor whites. Their religion also does not steep them theological constructs. Hence even Middle-class blacks lack skill in discursive reasoning, an area where Jews excel. Subjectivism reigns in place of reason. Asians, it seems. are not handicapped in this way. Their approach is objective.
I read a study once that indicated that the average income of black Catholics was higher than that of white Catholics (and much higher than that of non-Catholic blacks). This is probably because they are either a self-selected group that has had to make some effort to be Catholic or who have become Catholic as the result of sending their kids to Catholic schools, or were among the small group of born-Catholic African-Americans from Florida, Louisiana and other parts of the South that had had a Spanish or French influence.
