The fact that there are valid cases for divorce doesn't negate that fact that even in those cases there should be massive disincentives against it and that the overwhelming majority of divorces today likely should not be allowed because there is no valid reason for them. There's a lack of awareness about how destructive broken households and families are to children and society.uhm, what?
either there is a valid case for divorce or there isn't. you can't have it both ways. if there is a valid case for divorce then absolutely nothing should stand in the way.
preventing divorce on its own does not help fix broken households.
i do agree that as a socety we should do everything in our power to fix broken households. and by doing that, divorces will be reduced. but this is not done by disincentivizing divorce. it is done by removing the things that are the cause for the household to break.
"Money arguments are the second leading cause of divorce, behind infidelity"
the infidelity issue is addressed by better education (teach children that when they get married, their responsibility is to take care of each other (and teach them how to do that))
and the money issue is addressed by financial support for parents. it doesn't have to be UBI, but it should be to make sure that couples have enough money to live and raise children. in germany this is achieved by guaranteeing an existence minimum, and by unconditional extra money of around 200euro per child.
disincentivizing divorce by not financially supporting the single parent is a very bad idea because it forces them to remain in an abusive relationship.
