I’d put our legal system at the top of the list regarding the destruction of marriage. Women can basically whore-themselves-out for a short number of years, and then have a steady income flow, maybe for life. Men, of course, know this, and are responding as expected.
What planet are you living on? I know women who have had to spend their entire life savings and then live in poverty to defend against malicious custody suits brought by unscrupulous husbands and/or lawyers who knew she would do anything to keep her children from living at dad's house with the steady stream of loose women, drink/drugs and porn.
