John Wiener interviews Andrew Bacevich on our “empire of consumption” and the limits of Obama:

But he’s not one of those radicals who argue there is no difference between the Democrats and the Republicans. “I call myself an Obama-con, Bacevich says, “a conservative who will vote for Obama – because of the Iraq war. He has vowed that he will end the war and withdraw US combat forces. If he does that, it will render a verdict on the Iraq war: that it was a mistake and a failure. That verdict might open up the possibility for a debate about the fundamentals of US foreign policy. If McCain gets elected, the chances of us having that debate are close to zero.”

Interestingly for a self-identified conservative, Bacevich cites Jimmy Carter as the one president in living memory who really understood the predicament we face: an unsustainable way of life that drives our quest for military hegemony.

At the risk of being overly optimistic, though (not usually my problem), I have read some things recently that suggest that Obama may grasp the need for for a major shift in our economic life. This interesting piece on his economic philosophy, for instance, ends on this note:

Shortly after I boarded Obama’s campaign plane this month, one of his press aides warned me that the conversation might not last long. She explained that he was exhausted from two days of campaigning in Florida and might decide to nap as soon as he got on the plane. But a few minutes later he summoned me to the plane’s first-class section, evidently choosing an economics discussion over a DVD of “Mad Men,” which was sitting on his side table. His eyes were tired, and he looked a good deal older than he had only four years ago, on the night that he became famous at the 2004 Democratic convention. But we ended up talking for an hour. After I returned to my seat, the press aide walked back to tell me that Obama had more to say.

“Two things,” he said, as we were standing outside the first-class bathroom. “One, just because I think it really captures where I was going with the whole issue of balancing market sensibilities with moral sentiment. One of my favorite quotes is — you know that famous Robert F. Kennedy quote about the measure of our G.D.P.?”

I didn’t, I said.

“Well, I’ll send it to you, because it’s one of the most beautiful of his speeches,” Obama said.

In it, Kennedy argues that a country’s health can’t be measured simply by its economic output. That output, he said, “counts special locks for our doors and the jails for those who break them” but not “the health of our children, the quality of their education or the joy of their play.”

The second point Obama wanted to make was about sustainability. The current concerns about the state of the planet, he said, required something of a paradigm shift for economics. If we don’t make serious changes soon, probably in the next 10 or 15 years, we may find that it’s too late.

Both of these points, I realized later, were close cousins of two of the weaker arguments that liberals have made in recent decades. Liberals have at times dismissed the enormous benefits that come with prosperity. And for decades some liberals have been wrongly predicting that economic growth was sure to leave the world without enough food or enough oil or enough something. Obama acknowledged as much, saying that technology had thus far always overcome any concerns about sustainability and that Kennedy’s notion had to be tempered with an appreciation of prosperity.

What’s new about the current moment, however, is that both of these arguments are actually starting to look relevant. Based on the collective wisdom of scientists, global warming really does seem to be different from any previous environmental crisis. For the first time on record, meanwhile, economic growth has not translated into better living standards for most Americans. These are two enormous challenges that are part of the legacy of the Reagan Age. They will be waiting for the next president, whether he is Obama or McCain, and they’ll probably be around for another couple of presidents too.

Obama hit these themes pretty hard in his acceptance speech, but whether as president he would really be interested in using his clout to mobilize the country behind this kind of paradigm shift, and what that would look like, are, of course, big questions.
