MUCH of the time, argues David Runciman, a British academic, politics matters little to most people. Then, suddenly, it matters all too much. Donald Trump’s term as America’s 45th president, which is due to begin with the inauguration on January 20th, stands to be one of those moments.
It is extraordinary how little American voters and the world at large feel they know about what Mr Trump intends. Those who back him are awaiting the biggest shake-up in Washington, DC, in half a century—though their optimism is an act of faith. Those who oppose him are convinced there will be chaos and ruin on an epoch-changing scale—though their despair is guesswork. All that just about everyone can agree on is that Mr Trump promises to be an entirely new sort of American president. The question is, what sort?
Inside the West Wig
For sure, Mr Trump is changeable. He will tell the New York Times that climate change is man-made in one breath and promise coal country that he will reopen its mines in the next. But that does not mean, as some suggest, that you must always shut out what the president says and wait to see what he does.
When a president speaks, no easy distinction is to be made between word and deed. When Mr Trump says that NATO is obsolete, as he did to two European journalists last week, he makes its obsolescence more likely, even if he takes no action. Moreover, Mr Trump has long held certain beliefs and attitudes that sketch out the lines of a possible presidency. They suggest that the almost boundless Trumpian optimism on display among American businesspeople deserves to be tempered by fears about trade protection and geopolitics, as well as questions about how Mr Trump will run his administration.
Start with the optimism. Since November’s election the S&P500 index is up by 6%, to reach record highs. Surveys show that business confidence has soared. Both reflect hopes that Mr Trump will cut corporate taxes, leading companies to bring foreign profits back home. A boom in domestic spending should follow which, combined with investment in infrastructure and a programme of deregulation, will lift the economy and boost wages.
Done well, tax reform would confer lasting benefits, as would a thoughtful and carefully designed programme of infrastructure investment and deregulation. But if such programmes are poorly executed, there is the risk of a sugar-rush as capital chases opportunities that do little to enhance the productive potential of the economy.
That is not the only danger. If prices start to rise faster, pressure will mount on the Federal Reserve to increase interest rates. The dollar will soar and countries that have amassed large dollar debts, many of them emerging markets, may well buckle. One way or another, any resulting instability will blow back into America. If the Trump administration reacts to widening trade deficits with extra tariffs and non-tariff barriers, then the instability will only be exacerbated. Should Mr Trump right from the start set out to engage foreign exporters from countries such as China, Germany and Mexico in a conflict over trade, he would do grave harm to the global regime that America itself created after the second world war.
