The quote from the Chazon Ish in an earlier comment is something I heard expressed this way. He reportedly commented that the initial task of yeshivos immediately after the Holocaust was to re-establish Torah study. This meant focusing on the tzibbur – the population of the younger generation. But now (must have been prior to his passing which was in 1953) we have accomplished that goal, and our focus now must be on the individual.
My interpretation is that gearing to the masses is not the mission of chinuch any longer, and that the primary responsibility is to assist and guide each individual to achieve his maximum. I suppose if we had a perfectly verbatim quote, we would be in better to position to ascertain his intended message. If anyone can reference the exact wording, we all stand to benefit.
