History is hard!
Probably the best exponent of this style of debate is Owen Jones - who has carved out a particularly good little niche as the go-to guy for unreconstructed Bennism. Have a look at the following short paragraph from today's tirade against 'Thatcherism':
We are in the midst of the third great economic collapse since the Second World War: all three have taken place since Thatcherism launched its great crusade. This current crisis has roots in the Thatcherite free market experiment, which wiped out much of the country’s industrial base in favour of a deregulated financial sector.I count four 'facts' here and an opinion. While the opinion (that today's crisis has its roots in Thatcherite reform) is debateable, all four of the facts are flatly incorrect.
There have been three economic collapses since the Second World War
It's hard to be entirely sure exactly what Owen is talking about. Globally, there was a short shock in 1953, a more severe downturn in 1958, a global recession in 1973-5, a global recession in the early 1980s, another one in the early 1990s, a financial crisis in East Asia in 1997, a widespread recession in the early 2000s, and then the global financial crisis from 2007-8, with the long tail of recession following. Which three is Owen referring to?
All three have taken place since Thatcherism
Well, no. In the 34 years after the war, there were three distinct recessions (although for the UK, the entire 1970s was essentially one long crisis). In the 10 years of her time in office there were two. In the 23 years since there have been 3 (one of which the UK avoided entirely).
Thatcherism wiped out much of the country's industrial base
This is simply untrue.
