Heya, sorry to hear about your experiences. I know precisely zero folks who have been in that situation (wife leaving as soon as some money is made) but it sounds horrible. I do know folks who have been through divorce and I don't think it is as flippant a decision on anyone's part as you imply. My comment was based, as all comments are, on my experience.
I'm just saying there is a VERY good reason for intelligent young men to avoid marrage like the plague. The second you say, "I do" the countdown timer starts and divorce in America is broken, biased and expensive.
Lots of reasons for birth rates dropping, for sure, according to data: https://www.pewtrusts.org/en/research-and-analysis/issue-bri...
