I think one of the reasons why CTC/OAA/FTE are able to charge so much is access to money. In some ways, it's a bit like the housing market, when loans were easily accessible, prices went through the roof simply due to the fact that a lot of money was simply floating around, waiting to be borrowed.
Ten years ago, CTC was £60k with a type rating included, these days with a type rating it's double that. Modular, however, is still available for less than £50k. Now that loans are going to be less easy to obtain, hopefully the large integrated schools will have to re-think their pricing strategy and/or airlines will have to offer fully sponsored programmes in order to obtain a sufficient number of high-quality candidates.
