Earlier quoted context omitted.
Property taxes are awesome: they do not distort economic activity (if done right), and they are hard to evade (since you can't hide your land).
OK. So then I take it we can agree that they shouldn't be artificially capped for some people because they got here first.
(With the catch that you have to sell to any would-be buyer who offers to pay the reported value. Just to keep people honest.)
