Not by what your previous comment said.
Anyway, my other life is intervening. Gotta run.
My other comment spoke to the changing shapes and make-ups of families -- the nuclear family being replaced, at least in part, by the extended family. This is due largely to outside pressures. It's a solution to several problems, not the least of which are economic. I implied, but didn't outright state, that unwed mothers are what happens when solutions to those pressures aren't instituted.
