The Divorce Revolution: Has divorce become too commonplace?

Is there a Divorce Revolution going on? In her book The Divorce Culture, Barbara Dafoe Whitehead talks about the concept of the “divorce culture,” and she seems to suggest that divorce has become too commonplace, if not slightly glamorized. Is this true?
Well, it is hard to make the argument that divorce has not become commonplace, especially in places like New York, the United States, England, Sweden, France, Germany and other affluent cities around the world. Even in traditionally religious-conservative countries like Iran, 20% of marriages now end in divorce. Check out related posts here including divorce rates around the world:
But as a family law practitioner, would I call it a “divorce revolution”? Not necessarily because a revolution, to me, suggests a change that is sudden and abrupt. I don’t think the increasing divorce rates around the world are sudden and abrupt. I think it has been gradual, and I think it has been quite slow in some places as well, but I definitely think it has been steady in its increase as couples –women in particular — are no longer willing to settle for unhappy, unfullfilling and purposeless couplings till death do them part, when they can easily “do better.”
Sometimes, I wonder if maybe it is too easy to get married? I wonder if tougher guidelines should be placed on marriage so as to make sure that people who do go ahead with marriage are really people who not only want to get married, but who should get married? That would stem the divorce rate significantly. Maybe a marriage license should be effective for a year. And after the year, or some significant portion of time–like a learner permit for driving–then they can take a test and get the go ahead to get married if they still want to. Only after passing certain “tests” would that “permit” be permitted to be turned into a marriage. I think something like that would stem the so called “Divorce Revolution” right in it’s tracks.
