ofcourse:
1. would 70 R”Y count as “those in authority”. becuase they signed a letter clearly stating that Age Gap is the primary cause of the shiddcuh crisis.
2. the people redding the shidduchim are the MOST importnat ppl in this issue, becasue the boys will go out with the girls they are redd. if they hear names of 22 yr olds then they will go out with them. it they hear the names of the 19 year olds then they will go out with those instead.
In fact the ppl redding shiddcuhim (shadchanim and regualr ppl) play a far far greater role in alleviating the situation than anyone.
if you understood age gap properly you would understand why that is EXACTLY why the girls go running to shadhanim and the boys have no need to.
