Already, new forms of short-term and long-term rental housing are popping up in some metro areas. You can take on a house or apartment for a few months or even a year or two in developments that are striving to provide critical elements of community - schools, healthcare, social and cultural institutions - even for people who are living there only temporarily. People invested in a home, mortgage, or community are less likely to move to more economically vibrant locales. That kind of entrenchment is going to be an impediment to the coming spatial fix.

Beneath the surface, unnoticed by many, an even deeper force was at work—the rise of creativity as a fundamental economic driver, and the rise of a new social class, the Creative Class.

The creative individual is no longer viewed as an iconoclast. He—or she—is the new mainstream.

People don't need to be managed, they need to be unleashed.

We are the only major developed nation that isn't investing meaningfully in high-speed rail, and I believe we're making a mistake. Transportation systems that are fast and efficient and environmentally clean are going to enable the formation of these new mega-regions, the heart of the spatial fix. We need to be able to accelerate the movement of people, goods, and services - the very movement of ideas, knowledge, and creativity - between our major population centers. We have to build these links.

Denser cities are smarter and more productive

There's no getting around the fact that some cities face long odds, and governments and societies are going to be confronted with some hard decisions. Most importantly, cities have to recognize that in times of crisis they have to help themselves. Governments, no matter how well intentioned, can only do so much, especially when they themselves are so strapped for cash, as the U.S. is now. Government money will probably flow to cities and regions with good prospects for the future, so as not to risk money even further by pouring it into stalled economic models.
