Ok, this is just bad logic. Setting aside the actual figures. If "most women" are waiting until late in their life to have kids, the 1st, 2nd, and 3rd wife you marry, regardless of your age, is waiting until later in life to have kids.
Most women today yes. Most women in 30 years? Depends on a lot of factors. Given how poor genz is at 20 to the next generation the stability of living in a one family house vs working a minimum wage clerical job could well be worth giving up the idea of a career.
