1. constitutes a denigration of the institution 2. actually materially causes the decline in marriage rates we see, especially among the economically exploited.
Poverty causes significant stress on couples which almost certainly explains the differences between the marriage rates of different classes in our society. I'm pretty sure that people having kids out of wedlock aren't doing it because they read about it in GOOP or whatever. In fact, further down this thread someone has posted a survey which suggests that people more likely to get divorced actually have a stronger belief in marriage than people less likely to. This suggests strongly that it isn't the opinions of the upper classes that actually cause divorces and points to other economic causes.
