The Forbes claim is for citizens only. While most people are shocked at the low salaries for the unskilled expat workers, think of what they would be paid in their home countries if they were lucky enough to have a job. I brought two brother-in-laws from the Philippines here and they are making ten times what they would in PI. There is not a "successful" country on the planet that doesn’t have an exploitable work force and Qatar is no exception. I blame unscrupulous recruiters for charging huge recruitment fees and their home country governments for corruption and failing to bring industry.
