Some of these individuals are on Hong Kong A-scale and allowances, not paying tax in their home countries, extremely wealthy men by any standards, and are still too 'tight' to pay a few lousy bucks a month to the AOA to support their colleagues and attempt to maintain the contract that has been so good to them.
I like the way you automatically categorize every non-AOA individual as being too tight. Did you ever consider the possibility that the good majority left the AOA because they don't believe in what it stands for anymore. From past experience the most vocal AOA individuals were the ones to abandon their mates when the sh1t hit the fan, I suspect you would be no different.... but go on you can deny certain people the jumpseat if it makes you feel better.
