There most certainly is a Shidduch crisis! The fact that B’chesed Elyon there are hundreds and thousand of your people getting married all the time and the fact that Boruch Hashem they are zoiche to have children does not contradict this!
I cannot tell you how many young ladies I personally know that either are not married yet, or were married and are divorced. (I will not go into the reasons for the divorces. Even if the divorces are all “no fault” the fact is there are many single ladies)
My personal experiance is that as girls grow older they become more accomplished and, unfortunately the proportion of Bochurim that grow and accomplish proportionately to the females is very small. How many guys stay in yeshiva and really accomplish. But they do not want to leave for many reasons, even if they should. (There are those in Kollel that should no longer be there, but there is no purpose in discussing that)
There is a crisis, period. I will get frum here, and say when the RBSO resolves it, it will be resolved. Until then, it is incumbent on peole to do what they can. If you know any singles, THINK! Would any of them be Tzu Gepast for each other. If you only know Single boys, (Liek a rebbi in a yeshiva) Speak to peole and find out who the girls are and try to make shidduchim.
If you are a shadchan try to redd anyone you meet a shidduch, not just those where the reward for success is a motivational factor. (Trust me many shadchonim are pleasantly surprised when redding middle class shiudduchim, and disappointed when they expect to hit the jackpot!)
