Attention is therefore shifting to the second narrative, which suggests that the advanced economies’ fundamental capacity to grow by making useful things has been declining for decades, a trend that was masked by debt-fueled spending. More such spending will not return these countries to a sustainable growth path. Instead, they must improve the environment for growth.
The second narrative starts with the 1950’s and 1960’s, an era of rapid growth in the West and Japan. Several factors, including post-war reconstruction, the resurgence of trade after the protectionist 1930’s, the introduction of new technologies in power, transport, and communications across countries, and expansion of educational attainment, underpinned the long boom. But, as Tyler Cowen has argued in his book The Great Stagnation, once these “low-hanging fruit” were plucked, it became much harder to propel growth from the 1970’s onward.
Meanwhile, as Wolfgang Streeck writes persuasively in New Left Review, democratic governments, facing what seemed, in the 1960’s, like an endless vista of innovation and growth, were quick to expand the welfare state. But, when growth faltered, this meant that government spending expanded, even as its resources shrank. For a while, central banks accommodated that spending. The resulting high inflation created widespread discontent, especially because little growth resulted. Faith in Keynesian stimulus diminished, though high inflation did reduce public-debt levels.
Central banks then began to focus on low and stable inflation as their primary objective, and became more independent from their political masters. But deficit spending by governments continued apace, and public debt as a share of GDP in industrial countries climbed steadily from the late 1970’s, this time without inflation to reduce its real value.
Recognizing the need to find new sources of growth, towards the end of Jimmy Carter’s presidency, and then under Ronald Reagan, the United States deregulated industry and the financial sector, as did Margaret Thatcher in the United Kingdom. Productivity growth increased substantially in these countries over time, which persuaded Continental Europe to adopt reforms of its own, often pushed by the European Commission.
Yet even this growth was not enough, given previous governments’ generous promises of health care and pensions – promises made even less tenable by rising life expectancy and falling birth rates. Public debt continued to grow. And the incomes of the moderately educated middle class failed to benefit from deregulation-led growth (though it improved their lot as consumers).
The most recent phase of the advanced economies’ frenzied search for growth took different forms. In some countries, most notably the US, a private-sector credit boom created jobs in low-skilled industries like construction, and precipitated a consumption boom as people borrowed against overvalued houses. In other countries, like Greece, as well as under regional administrations in Italy and Spain, a government-led hiring spree created secure jobs for the moderately educated.
In this “fundamental” narrative, the advanced countries’ pre-crisis GDP was unsustainable, bolstered by borrowing and unproductive make-work jobs. More borrowed growth – the Keynesian formula – may create the illusion of normalcy, and may be useful in the immediate aftermath of a deep crisis to calm a panic, but it is no solution to a fundamental growth problem.
