"Capitalism isn't working" and why wealth disparity is the core reason.

Will Hutton in the Observer, review of Thomas Picketty’s book Twentyfirst Century Capital”: “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.
Piketty deploys 200 years of data to prove them wrong. Capital, he argues, is blind. Once its returns – investing in anything from buy-to-let property to a new car factory – exceed the real growth of wages and output, as historically they always have done (excepting a few periods such as 1910 to 1950), then inevitably the stock of capital will rise disproportionately faster within the overall pattern of output. Wealth inequality rises exponentially.
….The extravagances and incredible social tensions of Edwardian England, belle epoque France and robber baron America seemed for ever left behind, but Piketty shows how the period between 1910 and 1950, when that inequality was reduced, was aberrant. It took war and depression to arrest the inequality dynamic, along with the need to introduce high taxes on high incomes, especially unearned incomes, to sustain social peace. Now the ineluctable process of blind capital multiplying faster in fewer hands is under way again and on a global scale. The consequences, writes Piketty, are “potentially terrifying”.
For a start, almost no new entrepreneurs, except one or two spectacular Silicon Valley start-ups, can ever make sufficient new money to challenge the incredibly powerful concentrations of existing wealth. In this sense, the “past devours the future”. It is telling that the Duke of Westminster and the Earl of Cadogan are two of the richest men in Britain. This is entirely by virtue of the fields in Mayfair and Chelsea their families owned centuries ago and the unwillingness to clamp down on the loopholes that allow the family estates to grow.
….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.
….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.”
