Having traveled in the UAE and India I can confirm that as bad as things would be for these people in the UAE they're better off...*much* better off...than they'd be back home,certainly financially.It would take time to explain but it's somewhat similar to Mexicans illegally coming to the US.Their life is usually difficult (by our standards) but not nearly as difficult as in Mexico.The UAE *is* the moslem world's United States.The difference being that the typical Pakistani/Indian/Philippine has a genuine work permit for the UAE...not that that makes their lives particularly good.
I’ve been to the philippines, I get how they live, especially in some of the overcrowded cities, but I still can’t imagine wanting to work in a moslem country, especially given that they see what the moslems do back home.
