In an editorial published last week titled, “If Attitudes Don’t Shift, A Political Dating Mismatch Will Threaten Marriage,” The Washington Post’s editorial board points out that political polarization in this country has reached the point where it is now a prominent, often decisive factor in determining who Americans settle on as their potential mates. They emphasize this trend is now so acute it may actually threaten the institution of marriage as a whole. In particular, it seems that Democratic women are rejecting potential Republican suitors not only for marriage but as relationship material, all across the board. The message the editorial conveys—perhaps hyperbolically, perhaps not—is that as a consequence of this shift in attitudes, marriage itself in this country is in jeopardy.
That's also self correcting.
Huh, I wonder if that subtly influenced the whole "first born son inherits the land, younger brothers get shipped off to the clergy" thing back in feudalism.
That was mainly just to keep inheritance simple.
