If it turns out that it is specifically families led by women that are having more trouble making ends meet
What do you mean by "having more trouble making ends meet"? Between welfare programs and the occasional affirmative action job the women are perfectly capable of providing enough food for their children. It's just that the children are growing up feral, for lack of a better word.
Are you claiming that women who are alone cannot raise good kids?
That's contradictory. I thought raising kids was what women were traditionally described as good for.
Or are you claiming that women can only raise good kids when a man is present?
That's the best argument I've seen for stay-at-home dads, but I bet you'd see that as a degeneration of the good old values.
Or are you claiming that men are the indispensable and irreplaceable moral compass of a family?
Now that's bovine feces, for lack of a better word.
Speculation is important for forecasting; it's also fun. Speculation is usually conveyed in two forms: in the form of an argument, or encapsulated in fiction; each has their advantages, but both tend to be time-consuming. Presenting speculation in the form of an argument involves researching relevant background and formulating logical arguments. Presenting speculation in the form of fiction requires world-building and storytelling skills, but it can quickly give the reader an impression of the "big picture" implications of the speculation; this can be more effective at establishing the "emotional plausibility" of the speculation.
I suggest a storytelling medium which can combine attributes of both arguments and fiction, but requires less work than either. That is the "wikipedia article from the future." Fiction written by inexperienced sci-fi writers tends to generate into a speculative encyclopedia anyways--why not just admit that you want to write an encyclopedia in the first place? Post your "Wikipedia articles from the future" below.
