There seems to be far to much suspicion around as to motive.
I don't think the motives are particularly opaque.
VFR pilots want easy VFR privileges and (for the most part) they couldn't care less if IFR pilots got shafted.
Some might say that IFR pilots want easy IFR privileges and (for the most part) they couldn't care less if VFR pilots got shafted, but this is actually untrue since all IFR pilots know full well they are a small group and that if VFR GA is shafted then they are gone as well.
Farm strip pilots, operating as they usually do in relatively secure and secluded groups, want to continue their way of life and (for the most part) they couldn't care less if the rest of GA (and all their expensive airports with towers and ATC and landing fees) got shafted.
Permit pilots want their regime to continue and (for the most part) they couldn't care less what happens to the CofA crowd.
And so on.
A typical owner/pilot has climbed a helluva mountain to get where he is. Even VFR (a plain PPL) is a year's worth of hassle and frustration. Then, more hassle trying to do something useful with the piece of paper. It's no wonder that people who have "made it" this far are going to defend what they have achieved.
There is no way out of this, other than to create a regime in which GA can exist in a secure and predictable manner. Once you have this (as they have in the USA) then people will get on a lot better, each playing with what they enjoy, and a single body could represent the lot.
At present there is this perception that the CAA is out to screw everybody. This is quite wrong; the CAA is a good supporter of GA but they have some awful internal politics and funding issues to deal with.
But this problem exists in every other European country
AFAIK. It isn't going to go away. Maybe, many years from now, things will get better, but by then the property sharks will have shut down most GA airfields.
