Avira > Rav Belsky > Most overall should go to high school and not more; some should skip that, and others should even go to college.
what year was that? Probably the year that this corresponded to statistics of middle class in general. Similarly, R Feinstein reasoned hat one does not need college to live respectable/middle-class lifestyle.
Now, apply this to current day statistics, things are not that clear. Majority of middle class go to college, although for some of them it is not helpful or helpful just to claim credentials to do a job where high school only is required. But, overall, you can’t simply apply previous generation criteria without analysis.
