Dear Squeak,
Do you deny that
1. younger grades are than older grades for both girls and boys(population growth).
Please don’t, because a school study done by the Avi Chai foundation of all Jewish Schools in North America proved this without a shadow of a doubt.
2. Do you deny that: In the non chassic world Girls start dating 18-19 and boys appox 22-23.
in other words we have the equivalent of 12th grade boys dating ninth grade girls. Simply put every year there are more girls entering the dating pool (otherwise known as shidduch island) than boys.
If on the island there are 100 boys (12th graders) and 150 girls (9th graders), I guarantee you that 50 girls aren’t getting off the island.
Subjective factors such as education, personality, looks, money, connections, etc. determine perhaps which 100 girls out of the 150 will get married. No matter how you slice 50 girls can’t married.
