far vos,
It’s about 3% a year, the 10% number out there is cumulative, accounting for the 3 or 4 year typical age gap between husband and wife. If it were 10% a year, we’d really be in “g’hokta tzuris”.
There won’t be any more girls getting married. They will just be DIFFERENT girls getting married. These different girls (i.e. older) will be taking the place of the younger ones.
True, but you’re still missing the point. The current system has the older boys “borrowing” from the younger girls. It’s like a Ponzi scheme*; the same number of girls get married either way, but with the current system, some girls nebach get left out at the expense of the younger, ever increasing population. With the proposed system, all of the girls get married, albeit a few years later. Those few tears are, in effect, being distributed to the girls who wouldn’t otherwise get married.
*No, I don’t mean it’s a fraud; it’s not. I mean to compare the math; in theory, a Ponzi sheme could go on forever, with everyone getting their money, as long as the supply of investors keeps growing at a certain pace (which it doesn’t, the reason why Ponzi schemes eventually fall apart).
