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.

Human creativity is the ultimate economic resource.

We have to acknowledge that we can't look to manufacturing or natural resources to drive growth like we have in the past. Human capital, talent, and knowledge are our most important resources now. Every city has hidden seeds of opportunity waiting to be nurtured. Places like Detroit, Cleveland, and Pittsburgh are among my favorite cities. They have great universities, clusters of innovation across a range of industries, and pools of innovative and creative talent to build on.

We need to remake and reinvent our housing system so that it supports the flexibility and mobility of our economic system broadly. Home-ownership is rewarded by the federal tax code, which made great sense when that piece of the American Dream, and all the consumption that came with it, was essential to rebuilding the economy. These days, however, it feels like a huge penalty to people who want to travel light within the new mobile economy without a mortgage to hold them back.

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

Denser cities are smarter and more productive

I call the age we are entering the creative age because the key factor propelling us forward is the rise of creativity as the primary mover of our economy.
