Divorce Rates

Watch Dr. Phil. He loves divorce and the high rates of it in the United States (and in other developed countries, such as South Korea and the EU). Often, these rates are linked to moral degredation. However, I wonder if increasing divorce rates are rather the result of other trends in society.
It isn't any secret that women have some more social liberties nowadays. More and more females work, and single mothers aren't scrutinized quite like Ms. Pryne was anymore. I wonder if divorce rates are results of this trend rather than moral degredation which people love to talk about.
More evidence of this is that in non-developed countries, where women remain repressed and religious stigma remains preminent, divorce rates have not increased as hey have in developed countries in the last half-century. I guess, maybe to frame the hypothesis a bit more clearly, the increase in divorce rates isn't a result of moral degredation: immorality has been around the whole time, but only now do women have a recourse against it.
