“The R”Y want to help older unmarried girls. So they suggest close in age marriages. And they suggest shadchanim provide more help for older girls.”
That is actually incorrect. The R”Y want to alleviate the problem going forward, not simply to help those that are presently single. Read the letter, that’s why they make a strong point to mention that age gap is the primary source of the crisis. I know this because because I know the people who approached the R”Y.
