Arabs are just devils. Hope she can squeeze as much money as she can get from them. After all its one of the richest families in the world.
I can remember at one time one of Gaddafi's sons was arrested in Switzerland for assaulting a hotel worker. Gaddafi brought the whole of the Libyan gov to bear on the Swiss and he had to be released. Wonder whether he can pull such moves now.

It's not that people don't learn, it's that they are in desperate situations and hope that they will end up working in a place that is not too bad.

Hope, the eternal food for the human soul. I recall reading that the lady had taken up the job in order to be able to pay off her dayghter's medical bills.

How many people successfully sell mandazis here?

Ignorance is thinking the way you do! Fine, there are people who are lured by the dreams of the flashy lifestyle but most see the possibilities of getting their families out of a rut. I know of a woman who worked for one of these Saudi families. Fortunately, she was not mistreated, she played her cards right and now all her kids are in the US leading good comfortable lives unlike the life of poverty/hardship they had at home.

The reason most people prefer to take the risk is they can see the outcome of the hard work. If someone came to the US and got a job wiping poo and working double shifts, at the end of the week they can see the results of their labor. If they are wise, in a very short time they can accomplish what chomaing maize or frying mandazi would never accomplish in YEARS.

That is the same reason Mexicans risk crossing the Rio Grande and the Arizona desert and they do so from a very early age (talking about 10yr olds )because they know what life is like at home and what it can be if they cross over.
