When an issue is falsely called a “crisis”, intelligent people tune out.
There is no shidduch crisis. If girls and boys marry sometime in their 20s, there is no crisis. If they marry in their 30s , maybe they pushed it off a bit, but this is still not a crisis. If they don’t marry and as a result don’t have children, that is a crisis. During the Yom Kippur war, 2800 soldiers were killed and 5600 were wounded. That was a crisis. The chareidi world is not in crisis, at least not in the marriage arena.
There is a long list of prominent Rabbonim, including many Gedolim, who married what nowadays is considered “late.” They were not in crisis. They married when they married. Chill out.
