Every unmarried young adult, in all cultures (gays excepted) feels their is a shidduch (or at least, a marriage) crisis. They have always felt this way. Strangely, the crisis seems to be resolved when they get engaged. Even Adam ha-Rishon has a shidduch crisis for a while.
Absent a disaster that kills most of one gender (such as war with only male casulties), the problem usually resolves itself.
If there was a “crisis” – within a few years we’ld hear about wedding halls going broke, and heddarim closing for want of students.
