Yes but learning a language should not be a major course of study unless you are going to be a translator. We are far behind in STEM fields, fund that study.
At least partly to be argumentative I’ll present this theory.
I think studying anything with great vigor is helpful. I imagine that a tradition of Talmudic studies in the Jewish subculture encouraged a set of attitudes and abilities that predisposed those immigrants to excel in fields that require academic credentials.
I have often been of the opinion that the education provided in my field (programming or computer science) was of very limited direct help to new employees. Most of what they need to know is taught on the job after they are hired. An intelligent hard working person with no prior experience would be a better new hire than a slow and lazy person with a university degree in IT.
Except for the self selection and lack of objective standards perhaps even Woman’s studies or Ethnic studies would serve.
