These workers have become near slaves. They leave home with opportunity in mind and find out their employer is going to charge them most of their salary for those awful living conditions. Those who try and leave are finding they dont even have money for the trip home.
When there are deaths the family gets a fat bill if they want the body returned home. Straight up extortion.
A few groups have gone over and reported on this. They have found it difficult to get many workers to talk about it out of fear of having an "accident" at work if they do. Qatar has built modern day slave labor and is going to get away with it.
