Ohhhhh peeples, WHAT a question! I'll be as brief as possible here, as I Thank you, for a fabulous "Hub Idea"....(How did you know I was wrestling with the BLOCK again?)
There are so many factors that can be suggested as possible causes that lend to the high divorce rate. "Working women," is one argument that certainly has been addressed, but it's a terribly weak one, when argued AGAINST.
If your question was in reference to issues of children and working Moms, this may be easier.
IMO, based on many years of "listening" to countless individuals, on the verge of divorce and/or already divorced, but seriously struggling to rebuild their lives......that a woman "works outside the home," is extremely LOW on the list of factors that play a part in divorce.
I will leave you with a powerful statement to contemplate and give you cause to look at the issue from another angle.
Just over the past 20 years, the divorce rate has increased incrementally by 40% (being frugal!).....Yes, that is astounding.
Going all the way back to when the stay-at-home-Mom was the norm.....COUPLES DIVORCED, AT A MERE FRACTION OF THE RATE. Endless studies of factual data have strongly debunked the possible belief that this "rate increase" has anything at all to do with whether a woman works or not. There are at least a dozen more realistic reasons, that hold this blame of shame.
In the past 15 years, at least, the number ONE reason, hands down, is infidelity.
