I think it may be useful in cases when divorce is the only way to solve problem. I mean, in some families one of parents may be agressive (reasons are different). It's told that divorce destroy children's psychik but agressive parents' negative influsence is greater.

Another reason why I think divorce may be useful is that sometimes couples break up because of new love and may be it's even better because if parents will be happy creating new extended family then children will be happy too.

The third reason is that they learn how to be flexible, tolerant, accept different people and manage conflicts.

In my opinion, it's better to graduate from a university of your country, than from any university abroad. Quality of education is not always good. Of course, you might enter Harward, Tsinghua or Seoul National University but that's not so easy, so probably you will not. And I guess there are many good universities all over the world, so most of peoples don't have to go abroad to get some better knowledge. Moreover, some countries don't admit degrees taken abroad, so if I graduated from Yelle I would have to take bachelor degree later in my own country in order to have opportunity to work.
