I don't think the Boomer generation led Millennials to turn out too poorly, short of perhaps failing to teach them parenting skills (which we see in some of the problems Zoomers are now having).

Many of the Boomers are still together, despite the social stigma of divorce being gone.

I would agree it is a different world, but I also think the stigmas of divorce back when forced many of the Boomers to work together to overcome their differences, similar to how arranged marriages work out.
