What a great idea lets go and spend money at CAE or GECAT without a job offer and be guaranteed what exactly?
Christ do you actually work for Ryanair? If the market takes a turn for the worst we will be much like anyone else, we'll all be worried about our jobs! What do you suppose he should do? Suddenly stop all training now because there is a chance of a downturn and effectively blow all the money he's spent up to now? Or buy a house and see his investment loose value as the housing market contracts like its doing now as you pointed out? Or even better join a proper airline as you mention and then get fired because you were last in so you are first out much like Virgin and SAS have done in the past. Cracking idea I wish you were my accountant!
If you want to get into RYR providing you are good enough and its not a given you will be given a job you will be in a much better off position than if you hadn't have done it.
