Socialism has always failed, and the Socialists always claim it's because the country was not Socialist enough!
I lived through the 3-day working week, rolling power cuts, rubbish piling up in the streets and virtually every council and industrial worker out on strike back in the 70s. This was the result of being insufficiently Socialist, apparently.
The Left always blame Thatcher for "closing down the mines" - she didn't. The previous LABOUR government closed almost three times as many as she did! The 1970s UK was an incredibly depressing place to live. We were all broke - taxed at insanely high rates. 1979 brought a government with some sense. It took almost 6 years to sort things out, but we headed towards virtually full employment, and one of the highest standards of living in the world.....
