Property taxes are indeed a direct tax on one of the most significant forms of wealth in the US. Most equity for the average American family is their home. It doesn't make sense to tax people with greater property and generational wealth a tenth as much as younger people with less wealth.

And yes, there should be and are higher taxes on tech workers, inasmuch that there should be and are higher taxes on people with greater incomes. To an extent, at least. That is also directly taxing income, as you said.

We've already seen the prosperity of the mid-20th century in regards to high upper tax rates and social spending, and we've seen the Kansas tax cut experiments when it comes to dropping them all and absolutely ruining the state. These aren't theories or opinions anymore, they are fact.

To clarify, I don't think taxes should be based on age or anything. But when you have something like prop 13, it isn't explicitly worded to tax people based on youth, but that is the obvious outcome of the situation. And that's ridiculous. A wise nation do not devour their young.
