If there was a “crisis” – within a few years we’ld hear about wedding halls going broke, and heddarim closing for want of students.
Does that make sense? No. So why are you saying it?
Chadarim would close down if there were progressively less kids. In fact though, the principal theory for the shidduch crisis is that there are progressively more kids.
In any event, to address OP: There is a numbers crisis, and there are more girls than guys. That doesn’t mean all the girls are open to dating all the guys though, for better or for worse. But nor does it mean all the guys are open to dating all the girls.
