When Iain Duncan Smith starting visiting to Easterhouse and steered the new Centre for Social Justice (CSJ) towards a Tory-analysis of poverty, he was hailed by many as a prophet. Finally, wrote breathless commentators, the ‘nasty party’ had found a route-map to Compassionate Converatism. Five years later, IDS is part of a government that is plunging one million children into poverty and is ramming through the House of Lords new laws that will cut help for 3.5 million disabled people. The Saint of Easterhouse has become the punch-bag of the Treasury. The route-map, is turns out, was a chimera.

But IDS is still standing in part because he stands on the foundations of the CSJ’s study. I might disagree about lots of their conclusions but I can respect the fact that they actually bothered to look at the problem. Reform of social security – currently one-third of public spending – is a big question. It demands and deserves deep thinking not a casual look. And that’s why the launch on 14 February of the Commission on the Condition of Britain [2]is so welcome, and why I’ll be following its work so closely. Back in the 1990s, the Commission on Social Justice at the IPPR was critical to Labour’s social security reforms in office. I hope we’ll learn just as much from the IPPR’s second big look two decades later.

The truth is major reform of the welfare state is mission critical to rebuilding Britain after the global financial crash; it’s crucial to creating a country where we end the trauma of the living standards crisis, and it’s crucial to renewing a shared sense that we really are all in this together. This is the frame that Jon Cruddas set out for One Nation Labour in an important speech at the Resolution Foundation this week; ‘earning and belonging’.

When the Beveridge Report was published seventy years ago in the middle of World War Two, it was swept off the shelves by a British public thirsty for a vision of what would come when peace was won. At the heart of Beveridge’s argument was the idea we needed social insurance to help working families deal with the exigencies of life that caused new pressures (like the costs of children) or caused a loss of earnings , like the mass unemployment of the 1930s.

Today, the challenge for social security is not simply to minimise disruption to earnings, it is to help families maximise the potential of earnings. Beveridge’s world-view was set during the Devil’s Decade of the 1930s. Our world-view must be shaped by the gigantic squeeze on earnings that means living standards for ordinary working families might not recover, according to the Resolution Foundation, until the 2020s.

The reality for Britain today is that right now, productivity is going up; corporate profits are going up; companies are piling up cash in their bank accounts at a rapid rate of knots. Yet real wages are falling. In other words, workers are producing more and earning less. If we’re to reverse this giant trend, we are going to need new strategies for full employment – because full employment is the best guarantee of rising wages. We’re going to need new strategies to help working parents – especially mums – juggle childcare and sustain their careers. We need new ways to help the over 50s stay in work. And we need a radically new approach to disability policy so that government actually puts a team behind disabled people helping them get on in life, not a bureaucracy against them locking away help.

The IPPR’s work couldn’t come at a better time. Half way through the Parliament it’s now clear, the Conservatives so-called welfare revolution is collapsing in chaos. It doesn’t help working families get on. Its making poverty worse. The DWP is no longer even able to organise work experience in Poundland, never mind complex change like Universal Credit. We’re determined to offer a bold alternative, that staunches the cost of failures and puts social security once more, back on the side of working people.
