Obviously your "club" has nothing to do with Canadian taxpayers or the bill payers would equal 670 members.
If 87% of the taxes are paid by 20% of people in the US I'm assuming it's more like 90% here. So the 200 pay 90% and then another 10% is shared among, maybe another 100-150. But those people pay tiny membership fees in comparison.
The non-fee paying members are pretty classless to demand a rate increase from the fee-paying members to pay for their goodies. I mean, talk about gall!
