Suddenly, there is a new economist making waves – and he is not on the right. At the conference of the Institute of New Economic Thinking in Toronto last week, Thomas Piketty's book Capital in the Twenty-First Century got at least one mention at every session I attended. You have to go back to the 1970s and Milton Friedman for a single economist to have had such an impact.
Like Friedman, Piketty is a man for the times. For 1970s anxieties about inflation substitute today's concerns about the emergence of the plutocratic rich and their impact on economy and society. Piketty is in no doubt, as he indicates in an interview in today's Observer New Review, that the current level of rising wealth inequality, set to grow still further, now imperils the very future of capitalism. He has proved it.
It is a startling thesis and one extraordinarily unwelcome to those who think capitalism and inequality need each other. Capitalism requires inequality of wealth, runs this right-of-centre argument, to stimulate risk-taking and effort; governments trying to stem it with taxes on wealth, capital, inheritance and property kill the goose that lays the golden egg. Thus Messrs Cameron and Osborne faithfully champion lower inheritance taxes, refuse to reshape the council tax and boast about the business-friendly low capital gains and corporation tax regime.
As a result, the burden of paying for public goods such as education, health and housing is increasingly shouldered by average taxpayers, who don't have the wherewithal to sustain them. Wealth inequality thus becomes a recipe for slowing, innovation-averse, rentier economies, tougher working conditions and degraded public services. Meanwhile, the rich get ever richer and more detached from the societies of which they are part: not by merit or hard work, but simply because they are lucky enough to be in command of capital receiving higher returns than wages over time. Our collective sense of justice is outraged.
The lesson of the past is that societies try to protect themselves: they close their borders or have revolutions – or end up going to war. Piketty fears a repeat. His critics argue that with higher living standards resentment of the ultra-rich may no longer be as great – and his data is under intense scrutiny for mistakes. So far it has all held up.
Nor does it seem likely that human beings' inherent sense of justice has been suspended. Of course the reaction plays out differently in different eras: I suspect some of the energy behind Scottish nationalism is the desire to build a country where toxic wealth inequalities are less indulged than in England.
The solutions – a top income tax rate of up to 80%, effective inheritance tax, proper property taxes and, because the issue is global, a global wealth tax – are currently inconceivable.
But as Piketty says, the task of economists is to make them more conceivable. Capital certainly does that.
