Hate to butt in on the argument here but everyone that goes for an interview with Ryanair know that (for a Cadet position) they are going to have to stump up the cash. At no point during the interview process does the TRE or whoever conducting the HR bit ask to see your bank balance or whether or not you are willing to pay for the Rating. It is taken as read that you are, otherwise you would not be at the selection process.
Therefore it seems to me that the selection process for Ryanair is based purely on ability and suitability for the job.
I'm off now, I'll leave you two to get back at it
