However, it's getting harder and harder to do so. The more I read, the more I realize that economics are inextricably tied to politics. Political policy has a deep impact on economic problems and activity.
It turns out Paul Krugman went through this journey. Here's an article I found to be a fascinating read, sent to me by commenter CD. I've included a few select quotes, but I encourage you to read it in its entirety.
For the first twenty years of Krugman’s adult life, his world was divided not into left and right but into smart and stupid. “The great lesson was the low level of discussion,” he says of his time in Washington. “The then Secretary of the Treasury”—Donald Regan—“was not that bright, and you could have angry exchanges where neither side understood the policy.” Krugman was buoyed and protected in his youth by an intellectual snobbery so robust that distractions or snobberies of other sorts didn’t stand a chance. “When I was twenty-eight, I wouldn’t have had the time of day for some senator or other,” he says....
When Krugman first began writing articles for popular publications, in the mid-nineties, Bill Clinton was in office, and Krugman thought of the left and the right as more or less equal in power. Thus, there was no pressing need for him to take sides—he would shoot down idiocy wherever it presented itself, which was, in his opinion, all over the place. He thought of himself as a liberal, but he was a liberal economist, which wasn’t quite the same thing as a regular liberal. Until the late nineties, when he became absorbed by what was going wrong with Japan, he believed that monetary policy, rather than government spending, was all that was needed to avoid recessions: he agreed with Milton Friedman that if only the Fed had done its job better the Great Depression would never have happened. He thought that people who wanted to boycott Nike and other companies that ran sweatshops abroad were sentimental and stupid. Yes, of course, those foreign workers weren’t earning American wages and didn’t have American protections, but working in a sweatshop was still much better than their alternatives—that’s why they chose to work there. Moreover, sweatshops really weren’t the threat to American workers that the left claimed they were. “A back-of-the-envelope calculation . . . suggests that capital flows to the Third World since 1990 . . . have reduced real wages in the advanced world by about 0.15%,” he wrote in 1994. That was not nothing, but it certainly wasn’t anything to get paranoid about. The world needed more sweatshops, not fewer. Free trade was good for everyone. He felt that there was a market hatred on the left that was as dogmatic and irrational as government hatred on the right....
Certainly until the Enron scandal, Krugman had no sense that there was any kind of problem in American corporate governance. (He consulted briefly for Enron before he went to the Times.) Occasionally, he received letters from people claiming that corporations were cooking the books, but he thought this sounded so implausible that he dismissed them. “I believed that the market was enforcing,” he says. “I believed in the S.E.C. I just never really thought about it. It seemed like a pretty sunny world in 1999, and, for all of my cynicism, I shared a lot of that. The extent of corporate fraud, the financial malfeasance, the sheer viciousness of the political scene—those are all things that, ten years ago, I didn’t see.”...

It was the 2000 election campaign that finally radicalized him. He’d begun writing his column the year before, and although his mandate at the outset was economic and business matters, he began paying more attention to the world in general. During the campaign, he perceived the Bush people telling outright lies, and this shocked him. Reagan’s people had at least tried to justify their policies with economic models and rationalizations. Krugman hadn’t believed the models would work, but at least they were there.
After the election, he began to attack Bush’s policies in his column, and, as his outrage escalated, his attacks grew more venomous. Krugman felt that liberals were unwilling to confront or even to acknowledge the anger on the right with some of their own, so he was going to have to do it.
People in the [Obama] Administration were sometimes frustrated by his criticisms. “Paul’s great strength is his pellucid clarity,” Summers says delicately. “The other side of it is that there’s a degree of complexity in the world that a President has to deal with that he sometimes misses in his search for clarity.” But Krugman could also be useful: if he supported something that the left was dubious about—the Senate health-care bill, for instance—he could bring a lot of people around. On the other hand, when, as was more often the case, it was conservatives who were holding out, he had no influence at all. “I was actually in the room when many of the final negotiations”—over the stimulus package—“were done, and there was no way that a larger package would have gotten sixty votes,” an Administration official says. “Regardless of whether he is academically correct, it just wasn’t in the cards.”
