Yet, resilient as the growth record has been, there are shadows. The middle class has seen its post-tax incomes rise by less than those of both the poorest and the richest. A group of people have fallen into hard times. The share of prime-age American men who are not in work has been rising for years and is higher than in Britain, France and Germany. And life expectancy in America lags shamefully behind others in the rich world, mainly on account of too many younger people dying from drug overdoses and gun violence. Tackling such problems should be easier when the economy as a whole is growing. But America’s poisonous politics are no help.
In addition, the more that Americans think their economy is a problem in need of fixing, the more likely their politicians are to mess up the next 30 years. Although America’s openness brought prosperity for its firms and its consumers, both Mr Trump and Mr Biden have turned to protectionism and the politics of immigration have become toxic. Subsidies could boost investment in deprived areas in the short term, but risk dulling market incentives to innovate. In the long run they will also entrench wasteful and distorting lobbying. The rise of China and the need to fight climate change both confront America with fresh challenges. All the more reason, then, to remember what has powered its long and successful run.
America’s $800bn climate splurge is feeding a new lobbying ecosystem.
