Practical concerns is not rationalization. It must be nice to be rich and be able to afford hundreds of thousands in costs. Not all can do that.
IMO anyone can afford a divorce. Many men reject the concept of payments to support not only to wives who stayed home to raise the kids, but even the kids.
Our whole society is far too tied to material wealth at this point. How many farm out the raising of their babies and small children to daycare, so they don’t lose the benefit of a double-income household?
