> Jews last generation, come from elites from their previous family homeland who successfully migrated to escape bad government or seeking greater opportunity, when it was tactically hard to do so for the average person. It's a natural filter for smart, capable, effective people who can raise children to be same. The large majority of the US Jewish population came after the 1850s. They were not selected for wealth. Like the Irish immigrants were negatively selected. They were less educated than those who stayed at home, on average. Similarly Italians in the relevant period of mass migration. The middle class were doing well so they were more likely to stay home. > The effect tends to fade over time (shirtsleeves to shirtsleeves, or docks to docks, in three generations). This has no basis in evidence. Every psychological trait I’m aware of is strongly heritable, including ones with obvious impacts on earnings like intelligence, conscientiousness and extraversion[1].

If you want to know more about the extraordinary persistence of social class see Gregory Clark’s work[3].
