I've known several people who lost jobs in banking and finance and were then unable to find comparable jobs because of market contraction, and no other organization wanted to pay that kind of salary, which is one of those economic issues Beeza mentioned. Evo has mentioned changes in her industry in which high paid professional making something like $250 K find themselves out of a job, and likely unable to find a comparable position and salary. That unfortunately is a harsh reality these days in which technology creates new but short term opportunities.
