Today, new problems have emerged in the process of resolving old ones, but the solution is not to go back to the past. Some people may long for an era when divorce was still hard to come by. The spread of no-fault divorce has reduced the bargaining power of whichever spouse is more interested in continuing the relationship. And the breakup of such marriages has caused pain for many families.
