Taxes paid was actually what was said.

If you read it again you will notice that technically he thinks that, to satisfy those who believe the wealthy don't pay tax, Canada could use a system to encourage the wealthy to claim income, where that is incentivized by being able to vote. Often the wealthy have no need for income as they already have so much wealth and can easily borrow against that wealth as cash needs present themselves. It is believed (at least as far as the thread went) that the wealthy currently don't pay tax, and thus would be unable to vote, or their vote would count for little, under the proposed since they don't have sufficient income to qualify.

Maybe worth mentioning that the founding fathers in the US believed only property owners should vote.
