What's the justification for a land value tax?

We can't ignore the fact that land is the property of the commons.

George Monbiot has written a passionate call for a land value tax in the Guardian today. Pointing out that the coalition has singularly failed to take any real attempt to increase tax revenue — with the Lib Dems reneging on their promise to raise capital gains tax to 50p, and both parties turning their nose up at the economically-beneficial revenue gains of a financial transaction tax — he suggests one final attempt to come up with a novel way of raising revenue which the government might support: a land-value tax.

He describes the benefits:

It stops the speculative land hoarding that prevents homes from being built. It ensures that the most valuable real estate – in city centres – is developed first, discouraging urban sprawl. It prevents speculative property bubbles, of the kind that have recently trashed the economies of Ireland, Spain and other nations, and that make rents and first homes so hard to afford. Because it does not affect the supply of land (they stopped making it some time ago), it cannot cause the rents that people must pay to the landlords to be raised. It is easy to calculate and hard to avoid: you can't hide your land in London in a secret account in the Cayman Islands. And it could probably discharge the entire deficit.

More importantly — for the purported aim of winning over the coalition government — he also cites the politico-philosophical background of the tax, in the words of Winston Churchill:

Roads are made, streets are made, services are improved, electric light turns night into day, water is brought from reservoirs a hundred miles off in the mountains – and all the while the landlord sits still. Every one of those improvements is effected by the labour and cost of other people and the taxpayers. To not one of those improvements does the land monopolist, as a land monopolist, contribute, and yet by every one of them the value of his land is enhanced. He renders no service to the community, he contributes nothing to the general welfare, he contributes nothing to the process from which his own enrichment is derived ... the unearned increment on the land is reaped by the land monopolist in exact proportion, not to the service, but to the disservice done.

In quoting Churchill, Monbiot may strengthen the ability of his argument to win over the marginal Conservative, but he weakens the overall power of the claim to the justice of a land-value tax.

Because in these days of massive private-sector involvement in the provision of public goods, it is harder to argue that the landlord in his role as land monopolist "renders no service to the community". Developers put up money for transport links, for schools, for shops, and for park land and open space. A good developer does, deliberately and directly, increase the value of the land on which they build. And, despite Monbiot's claim to the contrary, some developers do go so far as to create the land on which they build.

The better argument for why a land value tax is just is that land, unlike all other property, can only ever have its root in expropriation from the commons. Even in the case of artificially created land, the sea-bed from which it was raised was once the collective property of all human-kind, and was only later privatised. In Britain, the legal fiction around land ownership even promotes this idea: no-one but the crown actually owns land. No matter how big your estate, it is remains the actual property of the Queen.

In other words, a land value tax isn't only justifiable because of the effect of the state in increasing the value of land; it's also justifiable because, no matter how long ago that land was cordoned off and turned into private property, it was once part of the commons.

(In fact, of course, the longer that land has been privately held, the more justifiable a land value tax is. In recent centuries the state has sold land to private interests, at least ensuring that some of the gains were collectivised; but no-one was paid when the first nobles threw up walls around their estates a thousand years ago.)

But arguing political philosophy with the coalition also reveals the folly of trying to convince them on the benefits of a land-value tax, or indeed any tax. Because while the rhetoric is about shrinking the deficit, which new taxes help, the ideology is about shrinking the state. And if that's the aim, arguing about the value of various taxes will never win the fight.

The rise of the green mayor – Sadiq Khan and the politics of clean energy

At an event at Tate Modern, Sadiq Khan pledged to clean up London's act.

On Thursday night, deep in the bowls of Tate Modern’s turbine hall, London Mayor Sadiq Khan renewed his promise to make the capital a world leader in clean energy and air. Yet his focus was as much on people as power plants – in particular, the need for local authorities to lead where central governments will not.

Khan was there to introduce the screening of a new documentary, From the Ashes, about the demise of the American coal industry. As he noted, Britain continues to battle against the legacy of fossil fuels: “In London today we burn very little coal but we are facing new air pollution challenges brought about for different reasons." 

At a time when the world's leaders are struggling to keep international agreements on climate change afloat, what can mayors do? Khan has pledged to buy only hybrid and zero-emissions buses from next year, and is working towards London becoming a zero carbon city.

Khan has, of course, also gained heroic status for being a bête noire of climate-change-denier-in-chief Donald Trump. On the US president's withdrawal from the Paris Agreement, Khan quipped: “If only he had withdrawn from Twitter.” He had more favourable things to say about the former mayor of New York and climate change activist Michael Bloomberg, who Khan said hailed from “the second greatest city in the world.”

Yet behind his humour was a serious point. Local authorities are having to pick up where both countries' central governments are leaving a void – in improving our air and supporting renewable technology and jobs. Most concerning of all, perhaps, is the way that interest groups representing business are slashing away at the regulations which protect public health, and claiming it as a virtue.

In the UK, documents leaked to Greenpeace’s energy desk show that a government-backed initiative considered proposals for reducing EU rules on fire-safety on the very day of the Grenfell Tower fire. The director of this Red Tape Initiative, Nick Tyrone, told the Guardian that these proposals were rejected. Yet government attempts to water down other EU regulations, such as the energy efficiency directive, still stand.

In America, this blame-game is even more highly charged. Republicans have sworn to replace what they describe as Obama’s “war on coal” with a war on regulation. “I am taking historic steps to lift the restrictions on American energy, to reverse government intrusion, and to cancel job-killing regulations,” Trump announced in March. While he has vowed “to promote clean air and clear water,” he has almost simultaneously signed an order to unravel the Clean Water Rule.

This rhetoric is hurting the very people it claims to protect: miners. From the Ashes shows the many ways that the industry harms wider public health, from water contamination, to air pollution. It also makes a strong case that the American coal industry is in terminal decline, regardless of possibile interventions from government or carbon capture.

Charities like Bloomberg can only do so much to pick up the pieces. The foundation, which helped fund the film, now not only helps support job training programs in coal communities after the Trump administration pulled their funding, but in recent weeks it also promised $15m to UN efforts to tackle climate change – again to help cover Trump's withdrawal from Paris Agreement. “I'm a bit worried about how many cards we're going to have to keep adding to the end of the film”, joked Antha Williams, a Bloomberg representative at the screening, with gallows humour.

Hope also lies with local governments and mayors. The publication of the mayor’s own environment strategy is coming “soon”. Speaking in panel discussion after the film, his deputy mayor for environment and energy, Shirley Rodrigues, described the move to a cleaner future as "an inevitable transition".

Confronting the troubled legacies of our fossil fuel past will not be easy. "We have our own experiences here of our coal mining communities being devastated by the closure of their mines," said Khan. But clean air begins with clean politics; maintaining old ways at the price of health is not one any government must pay. 

'From The Ashes' will premiere on National Geograhpic in the United Kingdom at 9pm on Tuesday, June 27th.
