I have the greatest sympathy for people who wish to be married and can not marry, due to a shortage of the opposite sex.
But, this doesn’t sound like that problem. This sounds like a question of either 1) changing standards on the part of the young women (they wish to marry “white collar” workers); or 2) We have a generation where there are many more accomplished girls than the previous generation.
Will our making more shidduchim help the problem? If there si still a shortage of spouses that meet expectations, then making a shidduch will only take one boy out of the boy pool, and one girl out of the girl pool, still leaving us with the initial problem.
Is the problem, really, that we have honored the kollel boys too much, and the working boys too little? Have we passed this attitude on to our daughers? There is nothing ignoble or unholy about honest manual labor. After all, if your toilet is backed up,
who do you call? The rabbi, or the plumber?
A more realistic solution would be to match girls with higher expectations with charming and hardworking boys, so they can see that such a match may be for them.
