These guys that put a downer on this deal have either been turned down already by CX or fly for other companies, don't like what thay have but can't get DESO or DEFO positions and are trying to put you guys off the cadet route.
For your info, most of the guys you describe above, are putting reality into the discussion, and most ALREADY work for CX.
Stating cost of living facts and other numbers is not "putting a downer " on the deal........ and further to your estimate, after 6 years in CX, you will probably just be upgrading to Junior First Officer, and at the moment is not much more than a 10% increase!
