UK incomes are decoupling from economic health

Has the typical family gained from the UK's growth since the 1970s?

On both sides of the atlantic, there has been a relatively long-running debate about the extent to which "decoupling" – the failure of typical household incomes to grow at a rate matching the increase in GDP – has occurred.

The classic treatment of the topic compares GDP per capita to the median family income, as Lane Kenworthy did for the USA:

The difference is clear, albeit not entirely unsurprising (what the graph shows is largely the result of the large increase in income inequality since the 1980s). Yet not everyone accepts that it demonstrates a real phenonmenon.

Kenworthy writes:

One objection is that the price deflator typically used to adjust GDP per capita for inflation differs from the deflator used for median family income. I’ve addressed that here by using the same deflator for both.

A second concern has to do with GDP per capita as an indicator of economic advance. Since the 1970s a larger portion of GDP has gone to replace old capital equipment and therefore can’t go to household income. Also, the number of persons has increased less rapidly than the number of households, so a per capita (per person) measure of GDP could mislead.

A third worry is that the income measure used to calculate median family income is too thin. If a growing portion of GDP has gone to employer benefits, that would help middle-class households, but it wouldn’t show up in these income data.

He addresses the second and third concerns by using a per-household measure, which includes in-kind payments and the effects of taxation. The result is a very similar graph:

This demonstrates, he says, that "decoupling is real and sizeable".

But what about the UK? Have we got the same problem? Yes:

All the data comes from the ONS, the inflation measure used is RPI, and both median and mean household income are taken measured from after the application of taxes and distribution of benefits.

Just as in the US, income growth for middle-class households has become decoupled from growth of the economy.

The Future of the Left: trade unions are more important than ever

Trade unions are under threat - and without them, the left has no future. 

Not accepting what you're given, when what you're given isn't enough, is the heart of trade unionism.

Workers having the means to change their lot - by standing together and organising is bread and butter for the labour movement - and the most important part? That 'lightbulb moment' when a group of workers realise they don't have to accept the injustice of their situation and that they have the means to change it.

That's what happened when a group of low-paid hospital workers organised a demonstration outside their hospital last week. As more of their colleagues clocked out and joined them on their picket, thart lightbulb went on.

When they stood together, proudly waving their union flags, singing a rhythmic chant and raising their homemade placards demanding a living wage they knew they had organised the collective strength needed to win.

The GMB union members, predominantly BAME women, work for Aramark, an American multinational outsourcing provider. They are hostesses and domestics in the South London and Maudsley NHS Trust, a mental health trust with sites across south London.

Like the nurses and doctors, they work around vulnerable patients and are subject to verbal and in some cases physical abuse. Unlike the nurses and doctors their pay is determined by the private contractor that employs them - for many of these staff that means statutory sick pay, statutory annual leave entitlement and as little as £7.38 per hour.

This is little more than George Osborne's new 'Living Wage' of £7.20 per hour as of April.

But these workers aren't fighting for a living wage set by government or even the Living Wage Foundation - they are fighting for a genuine living wage. The GMB union and Class think tank have calculated that a genuine living wage of £10ph an hour as part of a full time contract removes the need for in work benefits.

As the TUC launches its 'Heart Unions' week of action against the trade union bill today, the Aramark workers will be receiving ballot papers to vote on whether or not they want to strike to win their demands.

These workers are showing exactly why we need to 'Heart Unions' more than ever, because it is the labour movement and workers like these that need to start setting the terms of the real living wage debate. It is campaigns like this, low-paid, in some cases precariously employed and often women workers using their collective strength to make demands on their employer with a strategy for winning those demands that will begin to deliver a genuine living wage.

It is also workers like these that the Trade Union Bill seeks to silence. In many ways it may succeed, but in many other ways workers can still win.

Osborne wants workers to accept what they're given - a living wage on his terms. He wants to stop the women working for Aramark from setting an example to other workers about what can be achieved.

There is no doubting that achieving higher ballot turn outs, restrictions on picket lines and most worryingly the use of agency workers to cover strikers work will make campaigns like these harder. But I refuse to accept they are insurmountable, or that good, solid organisation of working people doesn't have the ability to prevail over even the most authoritarian of legislation.

As the TUC launch their Heart Unions week of action against the bill these women are showing us how the labour movement can reclaim the demands for a genuine living wage. They also send a message to all working people, the message that the Tories fear the most, that collective action can still win and that attempts to silence workers can still be defeated.
