Suppose we do what we do to prevent drug use and apply that to divorce. From herein,if anybody divorces, they will be sentenced to five years imprisonment. If there are too many divorces still, then we will keep amping up the punishment, until we achieve a national goal of zero divorces, including up until the death penalty.
Do you believe that we will achieve our goal of zero divorces, or do you think people will simply,become much more clever about murder?
