In any case, there is lots of room for experimentation at the margins and any Georgist reform won't be complete or overnight. Any shift from taxing labor and capital will result in a better and more efficient economy, so don't get too caught up in the abstract end state.
That fixes my biggest complaint about Georgism.
Take Google, for instance. What is the basis of their income? It's not the land they own or occupy. It's that they own google.com.
Where does IBM's money come from? Not from the land they own in upstate New York. It comes from their patent portfolio.
Natural resources are consumed inputs and don't generate rents (extraction rights, which are a subset of property rights in land, do); intellectual property isn't land in the usual economic sense (it is not naturally occuring, so not land; it is durable and created, and therefore capital in the classic division.) It does generate rents, but that's typical of capital goods generally.
(In modern use it's more typical to expand the use of “capital” to include land and thereby encompass durable, rent-generating subjects of property rights than to expand “land”.)
And yes, neoclassical economics classes land under capital and that is a fundamental disagreement of Georgist economists with neoclassical economists.
Perhaps, but your proposed construction (I’m not familiar enough with Georgism to know if it is the standard there) seems to be equivalent to that in equating classical categories of land and capital, but simply reversing the terminology, making durable (and thereby serving as rent-producing property) non-human factors of production, whether natural (and thus classically “land”) or created (and thus classically “capital”) all “economic land”.
I agree there are some other things you can tax. I presume those are also taxed at precisely the economic rents they create? My point is that government needs some sort of tax with a knob that they have the ability to tweak upwards or downwards based on shifting revenue needs. It seems to me the only things in a Georgist system are taxed at precise values and fail to give government that knob. Do all Georgist societies have some sort of services cap because their tax revenues are capped?
In any case, Georgism produces a very different financialization of governance than the current tax system, because public goods pay for themselves via increases in land value- see the Henry George Theorem by Nobel laureate Joseph Stiglitz: https://en.wikipedia.org/wiki/Henry_George_theorem. This means that rather than adjusting taxation to meet desired investment, desired investment is adjusted to produce optimum public returns- which has the beneficial side effect of incentivizing good and proper governance.
You already see this in areas that don’t prop 13 tax rates - as land values rise the land gets redeveloped.
I'd be very concerned about governments undertaking the necessary actions to drive land value taxes up by 22% over a four-year window. I think such policies would lead to many people being forced to vacate their land.
Even things like health care, which arguably keeps me healthy enough to work isn't distributed in any sort of uniform way so the productivity increase from it isn't likely to match the land value tax increase.
I think there are a lot of things that can increase land value 22%. I think some of them might even raise average wages 22%. I think almost none of them will raise each individual wage by 22%.
You have a thousand acres of farm farmed by your family and another say - ten workers in total.
The government builds a rail line and highway along one side of your farm and suddenly a portion of the thousand acres is better used as a small town - which now houses tens of families and perhaps a hundred workers.
Even if your personal income didn’t raise, the income of the area did.
Have we accounted for the fact that with LVT it's possible to get less tax revenue from land becoming vacant because the taxes become too high for users?
As for the tax being too high, if people started to vacate land that would mean the tax rate is over 100% of the land value (if it's at 100% people won't vacate, they won't be able to extract rents from it but it won't be an economic loss). Governments have every incentive not to tax land over 100% value because they actually lose money from doing so, so that's a pretty good security that it won't happen.
I worry that the overtaxation causing vacation mechanism isn't very efficient because if the tax takes a small part of the land value improvement it seems that the government gets additional unearned revenue while only land with little to no improvement would be vacated. I think people only vacate if the taxes cut into their additional revenues too steeply. I'm not sure exactly where the too steep point is, but I think governments would have an incentive to overestimate the value of land.
The question is to whom should this payment go, and "fee simple" is an entirely inappropriate mechanism for payment.
Everyone has an equal right to the use of land, limited only by the equal rights of others to use land. What the state does not need for the provision of public goods & services should still be collected and returned to the people on a per capita basis, as a simple matter of social & economic justice.
As for levies on externalities, these should be more accurately seen as correcting a market failure, the social cost that society must pay that the consumer/producer do not pay.
Notably, Frank Ramsey and A.C. Pigou can be considered crypto-Georgists -http://blog.lvrg.org.au/2013/09/ramsey-and-pigou-crypto-geor...
"As we shall see, Ramsey not only formulated a rule that leads directly to a “single tax” on land, but also anticipated the so-called Laffer curve in cases where the “single tax” is not employed. Moreover, Ramsey's rule was to be applied after any externalities had been internalized by means of appropriate taxes and bounties."
Georgists are a bit like libertarians when it comes to income taxes. It's very difficult for government to demonstrate a moral basis for interfering in work markets to generate taxation. Libertarians argue that if you are forced to pay 57% income tax you're 57% a slave. I'm not sure Georgists would go that far, but it seems unlikely you'd see implementation of taxes that are both economically less efficient and ethically more dubious than taxation of economic rents.
