Patience, the CAA didn't 'ratify' the ruling that made these courses compulsory. There was no choice available to them. It was a political decision that the UK would become part of the Joint Aviation Authority; once that decision was made, the CAA's role was to represent the UK within the organisation as it developed its regulations and standards. Once those regulations were agreed, there was no possibility of being able to choose which parts of Joint Aviation Regulations we accepted and which we didn't.
You might think it's unfair. You're entitled to that opinion, but your understanding of how it came to be is incomplete. As for your accusations of the schools running a 'neo-cartel', you are at liberty to ask the Competition Commission to investigate. However, as you are very new to this industry and its procedures, I would spend more time studying and less time criticising. When you have a genuine feel for how the industry works, you may be better placed to voice a considered and credible opinion.
Are you intending to be a crusader throughout your aviation career? If so, I wish you luck and fortitude. You'll need it! You'll also need a thorough understanding of your subject....
