A320rider. If it bothers you that much send your own money to help African kids!
My concience is clear. I earn MY money and spend it how I see fit. If that means a small fee to BALPA for a nice lunch, free coffee and a chance to meet airline recruiters, then thats my choice, as it is for all the other people who choose to attend.
I suggest you change your pessimistic outlook, and become more pro-active in your job search. If you have the resolve to do so.
