The cost of living is very high in Qatar, hence the reason why only a certain salary range is allowed to bring in family, which to me is a good idea.

Let say for instance, a husband with 3 kids, with a salary of 9k, honestly do you think it's enough? House, car, entertainment, food and others.

I'm more concern money going out could be more then money coming in. Which also could lead to an increase of sosial problems.

People do weird things when they don't have money, and this comes from my own experiences.
