Japan had their own bout with fiscal policy to stop a depression as little as 15 years ago. They built bridges to nowhere and even built highways that were parallel and right next to existing national highways. Imagine if we had another Interstate right next to Interstate 40 that runs from Wilmington, NC to Redlands CA. Now wouldn't that be something? Choice, that's the key.
Why not look at what worked for them and toss out what did not?
