If people really want to do something to help end the shidduch crisis, based on my personal experience, there are two (or three) things people can and should do. These are the two things that I think are the reason why I am not married yet (I mean, what seems to have led to it – only Hashem knows the reasons):
1. Try to be a good listener.
2. Stop speaking L”H and Motzi Shem Ra.
If I had the time and if it weren’t too personal and complicated, I could show you how the lack of those two things let to my being single, even though all of those responsible have no clue as to the connection.
If the oilam were to work on those two things, I have a feeling it would help put an end to the kids-at-risk crisis and the divorce crisis as well (and most other crises).
