I think the point of the comment re: slums is that often, people who come from a 'poorer' background are willing to put up with more to stay in a job they like, rather than going home at the first sign of trouble or that they don't like their work. If you're used to being in a country where the working conditions are good, then those people are possibly more likely to go home sooner because they have something better to go back to.
If your family are depending on you or if you don't like conditions where you came from, of course you want to work hard & put up with a few hassles to stay where you are. Don't get it mixed up with having a go at where you are from.
Anyway can we please get back to crew matters?? Have any of you been told you're going to be trained for the A380, or is it still on a voluntary basis? How are things going with the fleet, there were a few maintenance issues over the last few months, is it getting better?
