Even the masters of the neoliberal universe are beginning to fret about this, as Seumas Milne reports:

The billionaires and corporate oligarchs meeting in Davos this week are getting worried about inequality. It might be hard to stomach that the overlords of a system that has delivered the widest global economic gulf in human history should be handwringing about the consequences of their own actions.

But even the architects of the crisis-ridden international economic order are starting to see the dangers. It’s not just the maverick hedge-funder George Soros, who likes to describe himself as a class traitor. Paul Polman, Unilever chief executive, frets about the “capitalist threat to capitalism”. Christine Lagarde, the IMF managing director, fears capitalism might indeed carry Marx’s “seeds of its own destruction” and warns that something needs to be done.

The scale of the crisis has been laid out for them by the charity Oxfam. Just 80 individuals now have the same net wealth as 3.5 billion people – half the entire global population. Last year, the best-off 1% owned 48% of the world’s wealth, up from 44% five years ago. On current trends, the richest 1% will have pocketed more than the other 99% put together next year. The 0.1% have been doing even better, quadrupling their share of US income since the 1980s.

What they’re really worried about, of course, is that the hoi-polloi might finally tumble to what’s been going on. Democracy has a slow-burning fuse, but in some places, notably Greece, it’s beginning to fizz.

“Escalating inequality”, continues Milne,

has also been a crucial factor in the economic crisis of the past seven years, squeezing demand and fuelling the credit boom. We don’t just know that from the research of the French economist Thomas Piketty or the British authors of the social study The Spirit Level. After years of promoting Washington orthodoxy, even the western-dominated OECD and IMF argue that the widening income and wealth gap has been key to the slow growth of the past two neoliberal decades. The British economy would have been almost 10% larger if inequality hadn’t mushroomed. Now the richest are using austerity to help themselves to an even larger share of the cake.

But there is one area of the world where this grim cycle doesn’t appear to operate:

The big exception to the tide of inequality in recent years has been Latin America. Progressive governments across the region turned their back on a disastrous economic model, took back resources from corporate control and slashed inequality. The numbers living on less than $2 a day have fallen from 108 million to 53 million in little over a decade. China, which also rejected much of the neoliberal catechism, has seen sharply rising inequality at home but also lifted more people out of poverty than the rest of the world combined, offsetting the growing global income gap.

And the implication of all this? The economic system doesn’t have to produce inequality. It’s just one version of it that does. So we need a change in the system. And for that we need a new politics. The big question is when will it arrive? And will the current intensification of ‘security’ stop it in its tracks?
