Why the “economist as dentist” (“modest people who look at a small part of the body but remove a lot of pain”) model fails us in looking at the big picture:
That vision has in turn been undermined by the current crisis. It took extensive government action to prevent another Great Depression, while the enormous rewards received by bankers at the heart of the meltdown have led many to ask whether unfettered capitalism produced an equitable distribution of wealth. We clearly need a new, alternative vision of capitalism. But thanks to decades of academic training in the “dentistry” approach to economics, today’s Keynes or Friedman is nowhere to be found.
Another downside to the “dentistry” approach to economics is that important pieces of human experience can easily fall from sight. The government does not cut an abstract entity called “government spending” but numerous spending programs, from veterans’ benefits and homeland security to Medicare and Medicaid. To refuse to discuss ideas such as types of capitalism deprives us of language with which to think about these problems. It makes it easier to stop thinking about what the economic system is for and in whose interests it is working.
