Daas Zekainim Mibaalei Tosfos says on the inyan of Lot’s daughters – they said there is no one to marry us because they held they were meyuchasin.
I question whether this is not the same with some of the shidduch crisis. While it is true that there is definitely an issue with a disproportionate amount of boys to girls. However, what needs to be addressed is that many older singles tend to have very picky parents or are picky themselves and that no one is good enough. Not everyone is like this. But many. This has to be a problem that has to be addressed in the course of solving the problem.
