In fact, today’s economic troubles are not simply the result of inadequate demand but the result, equally, of a distorted supply side. For decades before the financial crisis in 2008, advanced economies were losing their ability to grow by making useful things. But they needed to somehow replace the jobs that had been lost to technology and foreign competition and to pay for the pensions and health care of their aging populations. So in an effort to pump up growth, governments spent more than they could afford and promoted easy credit to get households to do the same. The growth that these countries engineered, with its dependence on borrowing, proved unsustainable.
His prescription? A focus on “long-term sustainable growth.” Rajan writes: “The United States must improve the capabilities of its work force, preserve an environment for innovation, and regulate finance better so as to prevent excess.”
