If VAT was removed from commercial training, would the large integrated schools pass the savings on? There seems to be no limit to the number of youngsters with well-off parents who have "named their price" so to speak, many of them are presumably taken in by the marketing talk.
Ultimately, if P2F is to be ended and T&Cs restored, their needs to be a reduction in the number of new entrants to the job market. In the US, the 1500 hour rule has seemed to be effective, however there's not enough GA in the UK/Europe to necessarily make it work over here. Perhaps a requirement to pass a DLR-style aptitude test before sitting the ATPL exams would be more effective, with a waiver for ex-military folk or those with thousands of hours gained elsewhere.
