You don't seem to get it do you. Cathay does not pay its expats like other expats in HKG, i.e we do NOT get the Housing Allowance or Education Allowance as a lump sum to spend as we see fit. Leases, receipts etc are all required, in your world my friend the ICAC and Company would be all over you like a rash and I think your next home would be courtesy of the Correctional Services Department.
Wake up! You are not being done down you have EXACTLY the same basic salary and flying pay!!!, Take away your green eyes.
