C'mon, let's build

But no. We can’t simply write a check to the highway fund, we’re told, because that would increase the deficit. And deficits are evil, at least when there’s a Democrat in the White House, even if the government can borrow at incredibly low interest rates. And we can’t raise gas taxes because that would be a tax increase, and tax increases are even more evil than deficits. So our roads must be allowed to fall into disrepair.

If this sounds crazy, that’s because it is. But similar logic lies behind the overall plunge in public investment. Most such investment is carried out by state and local governments, which generally must run balanced budgets and saw revenue decline after the housing bust. But the federal government could have supported public investment through deficit-financed grants, and states themselves could have raised more revenue (which some but not all did). The collapse of public investment was, therefore, a political choice.

What’s useful about the looming highway crisis is that it illustrates just how self-destructive that political choice has become. It’s one thing to block green investment, or high-speed rail, or even school construction. I’m for such things, but many on the right aren’t. But everyone from progressive think tanks to the United States Chamber of Commerce thinks we need good roads. Yet the combination of anti-tax ideology and deficit hysteria (itself mostly whipped up in an attempt to bully President Obama into spending cuts) means that we’re letting our highways, and our future, erode away.
