I know people with kids that have divorced for the most stupid reasons.

In many cases I feel the problem could have fundamentally been solved by being better at dividing household work such that someone can rest one or two days and then switch.

For many divorce seems to be a way to divide labour, which they could have done without one.

It is undeniable that it seems that way for us as outside observers at least. It seems more like both are stubborn and would rather burn everything than take responsibility. It would have to be pretty bad on the inside for that external appearance of the divorce to be justified at all

That is true. I might be reading too much of my own pain point into their situations.
