Sandel’s politics are squarely on the left. In 2012, he added intellectual lustre to Ed Miliband’s renewal project for Labour, speaking to that year’s party conference on the moral limits of markets. The speech, and his book of the same year, What Money Can’t Buy, helped inspire Miliband’s critique of “predatory capitalism”, which was the Labour leader’s distinctive contribution to post-crash political debate in Britain.
But the main point of The Tyranny of Merit is a different one: Sandel is determined to aim a broadside squarely at a left-liberal consensus that has reigned for 30 years. Even a perfect meritocracy, he says, would be a bad thing. “The book tries to show that there is a dark side, a demoralising side to that,” he says. “The implication is that those who do not rise will have no one to blame but themselves.” Centre-left elites abandoned old class loyalties and took on a new role as moralising life-coaches, dedicated to helping working-class individuals shape up to a world in which they were on their own. “On globalisation,” says Sandel, “these parties said the choice was no longer between left and right, but between ‘open’ and ‘closed’. Open meant free flow of capital, goods and people across borders.” Not only was this state of affairs seen as irreversible, it was also presented as laudable. “To object in any way to that was to be closed-minded, prejudiced and hostile to cosmopolitan identities.” As he talks, the tone is as modulated as ever; the phrasing characteristically elegant and fluent. But a sense of frustration is palpable, as Sandel charts the rise of what he sees as a corrosive leftwing individualism: “The solution to problems of globalisation and inequality – and we heard this on both sides of the Atlantic – was that those who work hard and play by the rules should be able to rise as far as their effort and talents will take them. This is what I call in the book the ‘rhetoric of rising’. It became an article of faith, a seemingly uncontroversial trope. We will make a truly level playing field, it was said by the centre-left, so that everyone has an equal chance. And if we do, and so far as we do, then those who rise by dint of effort, talent, hard work will deserve their place, will have earned it.”
Fair competition does not constitute a just vision of society. Even if Trump is defeated in November’s presidential election, this is a truth, Sandel says, that Joe Biden, and his counterparts in Europe, must take on board. For inspiration, he says, they could do worse than turn to one of his intellectual heroes, the English Christian socialist RH Tawney.
What Money Can’t Buy sealed Sandel’s status as perhaps the most formidable critic of free-market orthodoxy in the English-speaking world. But as an age of violently polarised, partisan and poisonous politics has taken hold, it is that early encounter with Reagan that has begun to play on his mind. “It taught me a lot about the importance of the ability to listen attentively,” he says, “which matters as much as the rigours of the argument. It taught me about mutual respect and inclusion in the public square.”
The recommended way to “rise” has been to get a higher education. Or, as the Blair mantra had it: “Education, education, education.” Sandel homes in on a 2013 speech by Obama in which the president told students: “We live in a 21st-century global economy. And in a global economy jobs can go anywhere. Companies, they’re looking for the best-educated people wherever they live. If you don’t have a good education, then it’s going to be hard for you to find a job that pays the living wage.” For those willing to make the requisite effort, there was the promise that: “This country will always be a place where you can make it if you try.”

“Humility is a civic virtue essential to this moment,” he says, “because it’s a necessary antidote to the meritocratic hubris that has driven us apart.”
“Tawney argued that equality of opportunity was at best a partial ideal. His alternative was not an oppressive equality of results. It was a broad, democratic ‘equality of condition’ that enables citizens of all walks of life to hold their heads up high and to consider themselves participants in a common venture. My book comes out of that tradition.”

Donald Trump, who is a pernicious character. But my book conveys a sympathetic understanding of the people who voted for him. For all the thousands and thousands of lies Trump tells, the one authentic thing about him is his deep sense of insecurity and resentment against elites, which he thinks have looked down upon him throughout his life. That does provide a very important clue to his political appeal.
Michael Sandel was 18 years old when he received his first significant lesson in the art of politics. The future philosopher was president of the student body at Palisades high school, California, at a time when Ronald Reagan, then governor of the state, lived in the same town. Never short of confidence, in 1971 Sandel challenged him to a debate in front of 2,400 left-leaning teenagers. It was the height of the Vietnam war, which had radicalised a generation, and student campuses of any description were hostile territory for a conservative. Somewhat to Sandel’s surprise, Reagan took up the gauntlet that had been thrown down, arriving at the school in style in a black limousine. The subsequent encounter confounded the expectations of his youthful interlocutor.
“I had prepared a long list of what I thought were very tough questions,” recalls Sandel, now 67, via video-link from his study in Boston. “On Vietnam, on the right of 18-year-olds to vote – which Reagan opposed – on the United Nations, on social security. I thought I would make short work of him in front of that audience. He responded genially, amiably and respectfully. After an hour I realised I had not prevailed in this debate, I had lost. He had won us over without persuading us with his arguments. Nine years later he would get elected to the White House in the same way.”
