You need to tax the rich asshole so that he never gets to having 2M in disposable income in the first place, and leave poor grandpa out of it.

Taxing property is one of the most effective taxes to pay for local services because its impossible to hide the property you physically occupy within the zip code. All reasonable taxes are going to be need to be paid for by a broad spectrum of the tax base from rich to modest wealth to be at all realistic.

Taxing income to a greater degree is VERY HARD to implement both politically and legally. Can’t be realistically implemented at the county level at all. Is subject to all kinds of creative accounting, and may get an unpredictable amount of money back to the federal government but may not realistically fund the existing services that are being paid for as we speak in your county. EG if the government decides to buy more airplanes with it your school and fire department might have to close.

It’s just not a sound strategy to pursue. Any attempt to tax wealth is going to have to focus on property not exempt it.
