I think the crisis people have isn’t a crisis in shidduchim but a crisis in society as a whole. Whether it’s how people look at finance or how people look at relationships as a whole. Western society is decaying.
Want to know more idealistic solutions:
1. Not encourage women to pursue an education and instead, marry a man who has skills
2. Not frown upon someone who learns and works (which many of our sages did)
P.S. Men tend to marry women their age or younger but rarely older.
