Don't you think that 150 pilots A320 type rated unemployed ONLY in Spain, most of them with more that 1500 total time, are not a huge amount of them? If you add the ones from UK, France, Italy, Germany... you will have almost 1000 A320 pilots looking for a job. If you still consider an A320 type rating as a good investment, well....
And I am sure if you ask to most of them if they want they money back, I think that we all know the answer: OF COURSE.
