The real reasons for the increase in the divorce rate are:
Education and INDEPENDENCE of Women.
The welfare system in Western countries, where a state takes a responsibility to look after people once they get old. The family system is always stronger in poor countries, while children need parents and parents also need children in their old age in order to survive.
Vietnam is a non-religious country for centuries, where only 14% population follows any religion. Despite that, Vietnam has the lowest rate of divorce in the whole world.
Compare to non-religious Vietnam:
The divorce rate in Kuwait has reached 60% (link).
The divorce rate in Egypt, Jordan, Qatar, and UAE has gone above 35% (link).
Even in Saudi Arabia, the divorce rate has reached to 33% (link).
Islam stayed the same in these Arabic countries till today, but the Arabic countries became RICHER. Arab women don't need the financial support of their husbands to survive. Thus, they don't bear the exploitation by their husbands any more, and they get separated by taking a divorce (just like Western women).
In fact, the women still don't have full human rights in these Arabic countries, but only becoming rich made the divorce rate even higher than many western countries.
It may be due to the reason that marriages are still arranged in these Arabic countries, and people get no chance to find 'suitable' partner for them before marrying them. And since such arranged marriages are often 'mismatches', thus it may be one of the main reason for such a huge divorce rate in these Arabic countries.
Most Islamic countries are poor, and their Islamic Family System is based upon the 'Exploitation' of women
Keeping the family system intact through beating wives and their exploitation has no good in it.
Such an intact family system, where a mother is beaten and abused, will bring only DEPRESSION to children.
If Muslim men want to make the rate of divorce ZERO, then they should bear children only from Slave women
And there are some Muslims who are such stubborn that they openly say:
"The older system was better where a woman was not allowed to go outside the house. Now they go outside, get education, get self-dependent, and then they try to get their independence from their husbands through divorce. This is the main reason of increase of divorce rate in Islamic countries. This liberty to women should be stopped while children are being effected do to higher divorce rate."
If these Muslim men have problems with the rate of divorce, then they should not marry women, but they should take only "Slave Women" to their homes and bear children only from them.
Please be assured that Islam gave absolutely no human rights to the Slave women. In case of free Muslim wife, there are some chances of divorce, but in the case of slave women, your so-called Family System will become perfectly secure, and these slave women will never be able to break your family system.
And if you are unable to get slave women today from the outside world, then just snatch away all the remaining rights from your own free Muslim wives, and convert them in slaves, so that your family system stays stable.
All psychiatrists are unanimous that even a Single Parent is in a position to provide a 'Standard Upbringing' to children
The Children are totally safe in Western countries even in case of divorce too. In the case of separation, children are still in continuous contact with both the mother and the father, and both of them play a part in their upbringing.
Actually, all psychiatrists are unanimous that an intact family system is better for children, nevertheless, still a 'Single Parent' also has the full ability to provide such a 'Standard Upbringing' to children, in which children get all their rights, and then become a responsible citizen of the society.
This means, even a single mother is also in a position in which a child gets a standard upbringing.
The home of such a single parent is a much better place for the children, as compared to the home of an intact Muslim family, where the mother is abused and beaten and exploited day and night.
Although Muslims deny and try to find faults in the upbringing of a single parent, but we see that millions of Pakistani/Bengali/Indian Muslim men go to Gulf countries for JOB purposes, leaving their wives and children alone in Pakistan and their wives are upbringing their children alone as single parents, and these children don't see the faces of their fathers for years.
But when the same thing happens in Europe, and the mother has to up bring a child alone, then these same Muslims start declaring it Haram, and they start seeing a lot of problems in it, although in Europe fathers have a lot of contacts with the children despite living separately (i.e. children stay with fathers every weekend, and in holidays etc., which means they see their fathers much more than those Muslim fathers, who are living in Gulf countries due to their jobs.

Polygamy is worse than Monogamy
Polygamy is not in male nature at all. There is overwhelming scientific evidence indicating that polygamous societies are significantly worse off than monogamous ones. In fact, the reason monogamy has spread so much whereas polygamy has receded was because monogamous families were significantly more likely to produce successful offspring than polygamous families due to more parental investment in the children. Monogamy increases parental investment in children, which raises their emotional well-being and IQ. Children born to polygamous families are worse off in almost every indicator, and this extends to the wives and the husband too.
