This I disagree with. The facts are they can find dates with older guys. I and many guys I know would go out with these girls. The only reason they can’t find dates is because they are picky.
Where in the Torah does it say an excuse not to get married because the guy is 20 -30 years older? I discussed this in detail in my topic of “Who wants to be a Tzdaiekes like Rus?”.
But see http://www.theyeshivaworld.com/coffeeroom/topic/who-wants-to-marry-a-tzadeikes-like-esther
Also, your point is not relevant, since it does not negate the result that I am proving. If indeed the only way to match up all the girls with on a 1:1 ratio with guys is to match up 12 year old girls with 60 year old guys, then that shows a serious numbers mismatch.
