Unfortunately many articles don't really say anything other than the capitalist economy is cyclical with expansion and contraction.
What I find missing from these articles is not so much empirical data, but a false separation of the economic from the political. The thirty years of market fundamentalism marched alongside a profound shift in politics in both Britain and US. There is a hidden assumption that the upturn when it comes will take place in a political configuration akin to that of the 1990s or early 2000s.
The economic ideology that underpinned 1979-2009 has now fallen apart; unemployment, debt and poverty are multiplying. There is today a feeling of a phoney war as socio-political pressure builds up. It is highly unlikely that in the next half decade there won’t be major political changes which will themselves impact on economic structures.
