There is no shidduch crisis. Hashem already sets up every person with their zivvug/shidduch wife to be 40 days before they are even born. Forget about the fact that now were talking they are already approximately 20 years later since born and setup. The question YOU need to ask yourself is if your doing your RUCHNIUS hishtadlus of tefilla and bitachon and Emunah (faith and trust) in Hashem? And not just your gashmius hishtadlus of dating and speaking to shadchanim etc….
Daven directly to Hashem to send you or your child their Shidduch ASAP. Hashem already has them setup for many years since before birth and is just waiting for your call for help and for the right time
