Remember though, a lot of these profits were earned on the backs of minimum wage earners at places like Swissport, Delta Global Services, Simplicity, Republic, Endeavor, GoJets etc. I'm not saying its worse than what Emirates does, just saying a lot of people had to suffer through crap wages, no work rules, sick time etc.
Setting aside the rather significant fact of the workers you mention living in rather a more desirable (by most of the planet, anyway - there are always dissenters, like harry the cod) country versus the Middle East...
To compare the wages, work rules, sick policies, etc etc of those in the US at the lower end of the socioeconomic ladder, with those on the bottom rungs in the ME is just displaying a total lack of exposure or knowledge of the region. It's laughable. This is not to diminish the poor conditions for the contracted-out ancillary jobs in the US. But it's a bit like saying the poor folks in inner-city America are just like the poor on the streets of Kolkata or Dhaka.
Not so much.
