I'm not sure I buy that. Are divorce lawyers making people go to them? I don't live in the US, but where I live divorces are readily available and yet I haven't had one, nor do I feel a lawyer is pressuring me to divorce. But maybe you have a different kind of marriage.
No fault divorce opened up the flood gates.
I don't believe it either. It's the free market - people want the services that divorce lawyers are selling.
Remember, "covenant marriages," where offered, haven't been as popular as the regular kind. If people didn't want divorces, they wouldn't get them.
Any male who has any real knowledge of the divorce lawyer industry's festivities in store for husbands and fathers will not soon (if ever) marry. I am firmly believe this anti-male bias in the divorce courts in killing marraige.
