Book review: triumph of the city

A 

Triumph of the City, by Edward Glaeser, is a thrilling and very readable hymn of praise to an invention so vast and so effective that it is generally taken for granted. More than half the global population already live in urban areas and within twenty years, five million more will flood into the cities of the developed and developing worlds. The crowds and pollution and noise that choke modern cities may horrify us. They shouldn’t, says Glaeser: they are signs of growth, energy, and aspiration. Cities are our best and brightest hope.

B 

This idea has had more than two hundred years of resistance. Not long after the Industrial Revolution began in Britain, the Romantic poets turned away from the smoke and factories of their cities to celebrate the air and light of untouched nature. In 19th-century America, the writer Henry David Thoreau retreated to the wilderness of Walden Pond to live the solitary, simple life, and succeeding generations of Americans had cities were bad and nature was good.

C 

They had, Glaeser admits, a point. The early industrial cities were dirty, since they lacked efficient waste disposal systems, and diseases spread rapidly among the population. But more importantly they were profitable, and there were enormous commercial incentives to make them work, as well as political ones. Their transformation could be achieved at a stroke: in the second half of the 19th century, the French emperor Napoleon III gave Baron Haussmann unrestricted power to turn the slum-infested city of Paris into one of the wonders and delights of the modern world. Or the transformation could be done by trial and error. Glaeser has a brilliant account of the stop-start progression of New York. Its role as the 20th-century pole in this cultural and economic universe of the world. Either way, Paris, New York and other cities developed because they were the most effective markets for ideas and innovation.

D 

For these and many other reasons, we should not be so upset by the spectacle of urban poverty. The poor flock to cities in the hope of becoming richer (which, by and large, they did). They also invigorate the economy of the city. This does not excuse them but they allow property prices to soar with unreasonable planning regulations. Instead, cities should build more houses and thereby hold property prices in check.

E 

It can go wrong, of course. In Glaeser’s view, this is primarily because municipal authorities fail to understand the principal virtues of cities. The heart of Paris, as many Parisians say, is turning into a museum because of attempts to preserve Baron Haussmann’s 19th-century boulevards. Glaeser defends their preservation but argues that in the 1950s the French made a mistake in developing a huge high-rise, commercial area of La Défense on the outskirts of the city. He believes they should have revitalized the central area of Montparnasse into a new commercial district. This would have revived much of the city centre without destroying its fabric. In India, Mumbai could easily benefit from new areas of infill and the height restrictions could be relaxed by raising the limits presently imposed on the height of new constructions.

F 

In America, it is the suburbs that have proved to be the real disaster. Glaeser is repentant on this subject himself. He moved to the suburbs when he had children. His entirely legitimate excuse is that the government made him (and millions like him) do it. By under-taxing petrol and imposing tight planning restrictions on inner cities, while forcing up the cost of property, it made flight to the suburbs more or less inevitable for the middle classes.

G 

This is a disaster because nothing is more inefficient than a suburb. Suburbanites mingle less, and lose the face-to-face contact that makes being in cities so much more economically powerful. Houses are costlier to heat and cool than flats, and suburbanites drive thousands more miles per year than city dwellers. Every aspect of life involves more consumption. This leads to the strongest and newest argument in favour of cities—they are good for the environment. To live in the country or the suburbs is to have a vastly larger carbon footprint than an urban dweller.

Full of characters and accessible information, this is a tremendous book, not least because, like me, you will find yourself constantly seeking reasons to disagree. Like the poor in the city, this is a sign of success. If you hate the city and get moist-eyed at the thought of the country, then you are another, Glaeser is the man you will have to take on.
