Stewart Lansley in The Guardian:
During the past 30 years, a growing share of the global economic pie has been taken by the world's wealthiest people. In the UK and the US, the share of national income going to the top 1% has doubled, setting workforces adrift from economic progress. Today, the world's 1,200 billionaires hold economic firepower that is equivalent to a third of the size of the American economy.
It is this concentration of income – at levels not seen since the 1920s – that is the real cause of the present crisis.
In the UK, the upward transfer of income from wage earners to business and the mega-wealthy amounts to the equivalent of 7% of the economy. UK wage-earners have around £100bn – roughly equivalent to the size of the nation's health budget – less in their pockets today than if the cake were shared as it was in the late 1970s.
In the US, the sum stands at £500bn. There a typical worker would be more than £3,000 better off if the distribution of output between wages and profits had been held at its 1979 level. In the UK, they would earn almost £2,000 more.
The effect of this consolidation of economic power is that the two most effective routes out of the crisis have been closed. First, consumer demand – the oxygen that makes economies work – has been choked off. Rich economies have lost billions of pounds of spending power. Secondly, the slump in demand might be less damaging if the winners from the process of upward redistribution – big business and the top 1% – were playing a more productive role in helping recovery. They are not.
