Easy !
Wombat;
As has been said before don't take this out on other pilots, be they A scale or Local or whatever.
All of the policies come from management.
As long as someone is not taking more than the allowed allowance (ie max rental or owner occupier) then in my books it is up to them how they structure their tax issues etc. It is not a case of de-frauding CX at all.
It is more a case of what is taxable and what is not. Similar to what you would try and right off in other tax rich enviroments !
Try not to get to worked up about what someone else is up to. Get worked up about your COS and your job related issues and stay involved with the process.
Cheers
