Never-Married statistics. We are headed for about ~33% of people who will remain by themselves, for the millennial generation. Break this down farther, it results in over 50% of females and <25% for males...as males can import woman, migrate somewhere...
50% of females will end up alone, as single mothers...but never loved, considered, protected and idealized as a loving husband is known to do... If they become mothers, they will be on their own and solely responsible for how that kid turns out.
So, at some point, women will realize that they have done wrong for their own lives, and will advise the younger women. Gen X and Millennial women, who end up old and alone may be good counsel for the younger Gen Z, or better examples of "what not to do if you don't want to end up like them"
So, I think Gen Z women and men will have it a lot easier as the roles will once again be defined and enjoyed by each.
