In these tough economic times, it is sometimes hard to think of a silver lining. But Richard Florida proposes an interesting one: that what is bad for financial services firms may be good for artists and psychiatrists. I think he may be on to something.

In an essay in the latest Atlantic magazine, Florida suggests that New York City may not be as badly affected as some other US cities by the recession – despite being the home of Wall Street – because a lot of New Yorkers work in other industries, some of which are counter-cyclical.

Lean times undoubtedly lie ahead for New York. But perhaps not as lean as you’d think—and certainly not as lean as those that many lesser financial outposts are likely to experience. Financial positions account for only about 8 percent of the New York area’s jobs, not too far off the national average of 5.5 percent. By contrast, they make up 28 percent of all jobs in Bloomington-Normal, Illinois; 18 percent in Des Moines; 13 percent in Hartford; 10 percent in both Sioux Falls, South Dakota, and Charlotte, North Carolina. Omaha, Nebraska; Macon, Georgia; and Columbus, Ohio, all have a greater percentage of population working in the financial sector than New York does.

New York is much, much more than a financial center. It has been the nation’s largest city for roughly two centuries, and today sits in America’s largest metropolitan area, as the hub of the country’s largest mega-region. It is home to a diverse and innovative economy built around a broad range of creative industries, from media to design to arts and entertainment. It is home to high-tech companies like Bloomberg, and boasts a thriving Google outpost in its Chelsea neighborhood. Elizabeth Currid’s book, The Warhol Economy, provides detailed evidence of New York’s diversity. Currid measured the concentration of different types of jobs in New York relative to their incidence in the U.S. economy as a whole. By this measure, New York is more of a mecca for fashion designers, musicians, film directors, artists, and—yes—psychiatrists than for financial professionals. (via Felix Salmon)

These certainly seem to be boom times for psychiatrists, to judge by the number of suicides and evidence of acute stress in the financial industry and, anecdotally at least, New York is second to none as a centre for psychiatry and therapy.

Artists and creative types also seem to flourish in cities, particularly in the poorer and less developed areas where rents are cheap. That was the origin of the Manhattan loft, which went from being a preserve of poor artists in the 1970s to rich bohemians in the 1990s.

On the other hand, rents have to go down quite a lot first before the city becomes conducive to the kind of renaissance New York enjoyed in the wake of the 1973 crash. The New York Times this morning has a very bleak photograph of Bushwick in 1992, 15 years after the blackout riots.

As to London, maybe the picture is more mixed. I imagine it has just as great an opportunity for the creative industries to offset the financial one. On the other hand, the economy is probably more dependent on City jobs even than New York is on Wall Street.

The news of cholera outbreaks in Zimbabwe reminds me of reading The Ghost Map, Steven Johnson’s gripping account of the discovery of the causes of cholera in London in the 19th century. This was my review of it in the FT.

It seems improbable now that there could be cholera in Soho in the middle of London, but an outbreak there in 1854 led to the proof that the deadly illness was caused by drinking sewage-infected water.

It followed that cholera was entirely preventable, given clean drinking water. But the public water systems are breaking down in Zimbabwe, which marks a further downward step in that country’s deterioration under Robert Mugabe.

Update: As Derek Tunnicliffe notes in the comments below, cholera prevention is one of the aims of WaterAid, the charity the FT is supporting in its seasonal appeal this year. There is an article describing its work here.

Since I am the father of two members of the target demographic, I have just been to the cinema in Manhattan to see Walt Disney’s High School Musical 3. I quite enjoyed it (as did the demo) but the main thing that struck me as was how apposite it was to Barack Obama’s election.

A summary of the plot: a multi-racial bunch of kids at a high school in Albuquerque, New Mexico, put on a musical, indulge in innocent romance and plan to go off to college. The end.

Troy Bolton, the basketball-playing hero, is white. Gabriella Montez, his girlfriend and the leading lady, is Hispanic. His best friend, Chad Danforth, is black, as is Chad’s girlfriend Taylor McKessie, who is going to Yale to study political science and intends to become the US president.

They are, in other words, a perfect representation of the amiable multi-racial fantasy of many youth films in which the realities of discrimination do not intrude. They make the audience feel good about itself by presenting a sanitised version of reality.

This is not about business but, since it is a historic occasion, I will make an exception.

I watched Barack Obama’s victory in the presidential campaign tonight with friends in Fort Greene, a mixed race, gentrified district of Brooklyn. Then I walked back home after midnight.

I expected the atmosphere to be festive but it was more than that. There were crowds of people thronging the streets, whooping, singing and dancing. On one street corner, a bunch of drummers were beating out a rhythm and people were chanting “Ob-am-a” and “Yes, we can” to the beat.

It was made more colourful by a few police cars which turned on their sirens and flashing lights in an effort to clear the way, which only provoked more dancing and chanting.

People were hanging out of cars cheering and exchanging slaps of the hand with passers-by as they drove by. On another street corner, several people were amiably letting off firecrackers.

The whole thing felt like an explosion of pent-up emotion, like a city that had just been liberated. New York is, of course, a solidly Democratic city in a state that has Hillary Clinton as a senator.

It was an extraordinary sight.
