Writersoul, to tap into the musical chairs analogy*, if the ten girls who were left out were the ten with the worst hearing, giving them hearing aids would indeed even the playing field. But ten girls would be left out regardless, just likely not the same ten. So even if evening the playing field were possible (which is doubtful), it would not solve the problem, it would just shift it to other girls.
* I agree with ubiquitin that it’s simpler than the constantly changing shidduch field, but the essential numbers issue is still there.
