The cause of the crises is that every girl coming out of sem wants to marry a learning boy and all boys are told to stay in learning forever and to look for a father in law who can support them.
And the only reason why the boys can ask is because of the crisis. Without it, the parents of the girls would tell them to stick it to Sam Hill. Now they have no choice if they want their daughter to get married. I personally know of a number of cases. If I were a Posek (which I am not), I would say it is Karov to a ????????.
