A lot of local land rent leaves town, going into the pockets of absentee owners, family trusts, corporations, real estate investment trusts.  A lot of local mortgage repayments leave town, into the pockets of, for example, GM (Di-tech Funding), large banks and a lot of other corporations.  A lot of high-end Florida retirements are funded by buyers and renters in high-growth markets.  Meanwhile, young families struggle to pay high mortgages and potential entrepreneurs are discouraged by high rents, and a lot of centrally located land goes underused. 

A better alternative would be to keep that land rent local, and let it be the foundation of local spending on schools and infrastructure.

Everett Gross: Explaining Rent

Sometimes it's difficult for people to understand the meaning of "rent" as an economic concept. One way I have of explaining it doesn't use the word rent. I just use a little analogy.

I'm from Crete, Nebraska. It's a small town of 5,000 people.

Suppose a man comes to Crete, and he wants to start a business. He needs a building, but first he needs a piece of ground to build this new building on. So he looks up a real estate agent, describes what he wants, and the real estate agent shows him a parcel that's just right for his needs. The man asks the agent, "All right, now how much money do you want for this land?" The agent says, "It's worth $50,000." The man says, "Why is it worth $50,000?" And the real estate agent points out that "The school is good, the roads are good, the police department is good, the rescue crew is good and very fast, and business is good here."

So the man says "Yeah, I believe that $50,0000 is a fair price. I'll take it. How do I pay the $50,000 to the school people, and the road people, and the police department? To whom do I pay the $50,000?" And the real estate agent says, "Oh no. You don't pay it to them. You pay it to the person who owned the land before."

The man says, "But who supports the schools, and the roads, and the police, and the other good things?" And the real estate agent says, "If you build, then you'll pay for them again."

The buyer then asks, "And what will the previous owner do for me for my $50,000?"  The real estate man answers, "Nothing!  Nothing at all!"

Now I don't need to use the word "rent" in that explanation. ... see the whole story, including Dave Wetzel's version

Karl Williams:  Land Value Taxation: The Overlooked But Vital Eco-Tax

Charles T. Root — Not a Single Tax! (1925)

"If taxation is unnecessary, what is to take its place? Government and its functions are increasingly expensive. They require a lot of money. Where is it to come from?" The answer may be placed in the form of a second proposition:

Every community, whatever its political name and extent — village, city, state or province or nation — has its own normal, unfailing income, growing with the growth of the community and always adequate to meet necessary governmental expenditure.

To explain: Every community has an indefeasible original right to the land on which it exists, and to all the natural, unmodified properties and advantages of that particular area of the earth's surface. To this land in its natural state, undrained, unfenced, unfertilized, unplanted and unoccupied, including its waters, its contents and its location, every individual in the community (which may consist of any political unit selected) has an equal right, while all the individuals together have a joint right to the value for use which society has conferred upon these natural advantages.

This value for use is known as "Land Value," or by the not particularly descriptive but generally adopted name of "Economic Rent."

Briefly defined the land value or economic rent of any piece of ground is the largest annual amount voluntarily offered for the exclusive use of that ground, or of an equivalent parcel, independent of improvements thereon. Every holder or user of land pays economic rent, but he now pays most of it to the wrong party. The aggregate economic rent of the territory occupied by any political unit is, as has been stated above, always sufficient, usually more than sufficient, for the legitimate expenses of the government of that unit. As also stated above, the economic rent belongs to the community, and not to individual landowners.

On the other hand, the result of every utilization or enhancement of the natural advantages of land (such as farm profits, the rent and selling value of buildings and other improvements), when accomplished by an individual, belongs wholly to that individual, and should never, and need never, be taken from him by taxation. ... read the whole article

Fred E. Foldvary — The Ultimate Tax Reform: Public Revenue from Land Rent

Some may wonder why anyone would own land if most of the rent is taxed away. One would own land for the same reason people rent land: in order to use it. Ownership also gives the title holder rights of possession, the ability to control the use of the site indefinitely.

Today there is also a speculative motive for owning land, to profit from the increase in its price. With most of the geo-rent tapped for public revenue, the speculative motive would be dampened. That would benefit the economy, since with a lower price of land, funds that now go to buy land would instead go to build more capital goods, hire more labor, or provide better training.

The tax on the geo-rent would be borne by the owner, not the tenant. If a landlord, who was already charging what the market could bear, tried to pass on the tax, he would face vacancies. Some say that since the tax would be invisible to renters, the link between using public services and paying for them would be broken. But productive public services increase the geo-rent, so that link is there. If government revenue is wasted, then indeed this does not generate rent, and a land value tax without corresponding benefits would reduce land value. Pressure for a productive use of public revenue would come from the landowners more than from the tenants. But that is no different than the situation today; poor folks pay little or no income tax and no property tax, and typically they get government assistance. This is an argument not against the use of rent, but in favor of privatizing government programs. In the private sector, the link between ownership and control is stronger. ... read the whole document
