A million dollars for solutions but not one cent for figuring out the problem.
Because they already know what the problem is, and a primary cause.
Did they try? Did they hire consultants to figure it out? Did they try for a second best solution? How about pick 30 yeshivish boys schools and 30 yeshivish girls schools from the elementary school classes graduating in the 90’s and track them? That wouldn’t control for unequal numbers coming in, but would get us some info at least.
How about take one quick look at how many new schools/classes open every year in Lakewood, and realize that you have your answer right there.
