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 have to build these links.

Builders need to take their preeminent position back from the traders for the economy of the future to flourish.

New Jersey boasts the highest percentage of passport holders (68%); Delaware (67%), Alaska (65%), Massachusetts (63%), New York (62%), and California (60%) are close behind.

We need to do more to make service jobs into higher-paying family-supporting jobs of the future.
