You asked why LCCs want cadets despite the great number of unemployed experienced pilots out there? The previous couple of posts contain a big part of the answer. Because it's easy to give your own definition of "normalcy" to someone who doesn't know otherwise. Someone fresh out of flight school can obviously be made to believe that it's OK to make one pay for a TR and then send them on unpaid leave for 6-9 months. Why? Because he/she still hasn't seen anything different from that. Those are the very same people who are shocked to find out that other establishments provide their crews with accommodation at the company's expense when out of base and even with a free shuttle from the hotel to the airport.
