To mox and AZ, certainly this would have been a problem 100 years ago as well (vis-a-vis) the age gap. Is there a reason neither Chofetz Chaim nor R’ Chaim M’Brisk nor R’ Boruch Ber gave such an edict? Why not 30 years ago with the likes of R’ Moshe Feinstein, R’ Ahron Kutler and the Steipler?
Could it be because Chazal point out that there needs to be mechus darga in a relationship? They knew that this was essential in Shalom Bayis, and that it can be easily accomplished with a guy marring a girl who is younger. This is something CHAZAL have told us about marriage, I find it odd that you are trying to take on Chazal.
Please give real stats, not these pseudo point proving stats. Give at least a 10 year GLOBAL census proving your point (don’t tell me about the number of unmarried 21 year olds in Toronto, because more likely the males at that age are in Yeshivos out of Toronto, hence the false statistic)
As previously stated:
“There are three types of lies — lies, da** lies, and statistics.”
There are so many factors that go into making shidduchim, I find it weird you feel you are able to point to ONE factor and say “THAT’S IT!”
