"Imagine the outcry today. The president asks for $100 Trillion (in 2010 dollars) to upgrade the nation’s infrastructure. Congress approves the idea. Of course, the whole project takes more time and money than planned, and yet, a generation later, it is generally considered one of the country’s best investments. Unthinkable today, it happened in 1955, when Dwight Eisenhower asked for a program to build 40,000 miles of interstate highways.
Getting Congressional approval in 1955 wasn’t the political miracle it would be today. The economy was in better shape than now. Post-war America was generally more confident in its power to solve problems. Also, the project was launched by a popular, Republican president with strong bipartisan support."
