1st World - place where all third world pilots are trying to get to so they can have supposed job security and upgrade path...
2nd World - place where all first world pilots retire to escape the rat race and back stabbing....or got tired of waiting for upgrade.
3rd World - overflow from 1st world because 2nd was full...
Begs the question, if third is such a dump, why are they paying better and offering better opportunities. Methinks third is getting ready for a name change....
