That would have been true if property tax was still a reasonably small expense that wasn't too much of a burden on the average homeowner, but for me personally, my escrow payment is like a second car payment. I know that compared to most homeowners I still have it good.
There are many homeowners whose incomes are not growing fast enough to pay skyrocketing property taxes. Nobody mentions the homeowners who were able to make their mortgage payments only to be forced to sell their homes because property taxes got too high. At least a flat income tax is based on one's ability to pay.
I’m a fan of the flat tax - and I’d take it one step further. I would like the ability to direct my taxes to where I want them spent.
