From President Obama’s press conference yesterday:

I think the proposal that I put forward with respect to infrastructure is one that historically we’ve had bipartisan agreement about. And we should be able to agree now that it makes no sense for China to have better rail systems than us, and Singapore having better airports than us. And we just learned that China now has the fastest supercomputer on Earth — that used to be us. They’re making investments because they know those investments will pay off over the long term.

Again with China’s rail system. We posted this already, but here’s Robert Samuelson explaining why high-speed rail makes no sense in America. The opener:

Somehow, it’s become fashionable to think that high-speed trains connecting major cities will help “save the planet.” They won’t. They’re a perfect example of wasteful spending masquerading as a respectable social cause. They would further burden already overburdened governments and drain dollars from worthier programs – schools, defense, research.
Let’s suppose that the Obama administration gets its wish to build high-speed rail systems in 13 urban corridors. The administration has already committed $10.5 billion, and that’s just a token down payment. California wants about $19 billion for an 800-mile track from Anaheim to San Francisco. Constructing all 13 corridors could easily approach $200 billion. Most (or all) of that would have to come from government at some level. What would we get for this huge investment?
Not much. Here’s what we wouldn’t get: any meaningful reduction in traffic congestion, greenhouse gas emissions, air travel, oil consumption or imports. Nada, zip. If you can do fourth-grade math, you can understand why.

The rest here.
