California voters approved a $10 billion bond measure to support a high-speed rail system connecting the state's major cities. It was, and remains, a bold move in dismal economic times. But this kind of long-view planning has the potential to slingshot the state into a brighter fiscal future. Well done CA. It's time now for the rest of the US to get on board. The latest country to push ahead with high-speed rail plans: Vietnam. A $33 billion project will cut travel time between the country's two biggest cities--Hanoi and Ho Chi Minh--from 32 hours to about 10. And of course, it will eliminate so many gazillions of auto emissions.
