I'm a big proponent of Land Value Tax. In theory it is one of the healthiest forms of taxation since supply is fixed. It encourages efficient use of land and discourages owners from squatting on undeveloped land just to reap value from its location. https://en.wikipedia.org/wiki/Land_value_tax
I’ve heard economists champion the idea, but I’ve heard little talk about what the tradeoffs are. What are the downsides?
In order to compensate, tax on land is increased, so the relatively poorer homeowner who owns land with a relatively worthless house sees little benefit but in fact a tax increase, as the taxes that we’re previously being paid by the mansion owners fall onto them.
