The countless mitzvos in getting married are shoved aside in favor of pride and peripheral religious issues with full Rabbinic sanction. The “Shidduch Crisis” is caused by truly distinguished Roshei Yeshivah who unabashedly encourage their students to delay the age of Shidduchim, thus wrongly preferring the entire Yeshiva’s benefit over the Torah study and observance of individual man and women.
And as a symptom of the imbalanced present approach to money matters, the youth are made to reject any Shidduch that does not include a “deserved” apartment. Destitute fathers can hardly marry off their daughters without pledging money they don’t have — and are unable to obtain — without taking out questionable loans.
