Interesting, this matter of the airline demanding money up front for the privelige of working for them. But this sort of practice is actually very common in the business world. Usually its called 'buying a franchise'. For instance, if you were now qualified to sell financial services products (having passed all the necessary exams, etc) and applied to Zurich for a job, they will actually charge you £2,500 (the last figure I heard) to do the Franchisee induction course.
Looking back through history, too, one could buy a commission in the regiment of your choice. This would then entitle you to do the job, wear the uniform, and also get paid etc.
However, having stumped up with the cash to buy the position then you should be actually entitled TO SELL THE JOB ON (AT THE GOING MARKET RATE) to anyone who might be interested later.
