Thatcher destroyed manufacturing and industry in the whole of the UK. The north of England and Wales were trashed just as badly. She did that to Scotland, as well as the Poll Tax which caused riots. All the stuff she privatised has gone to shit - energy companies, the railways, British Telecom... Now they see Cameron privatising Royal Mail and the NHS too. Her policies failed utterly and lead to the global financial crash a few years back.
That's the view that sums up the Yes campaign, indeed. But is it realistic?
Let's start with "Thatcher destroyed manufacturing and industry". I find it to be a very misleading way to phrase things. At the time Thatcher came to power, heavily nationalised UK industry was already destroying itself. It had high costs, low productivity, large chunks of it were unprofitable and it was dominated by incredibly militant unions who didn't care about any of this at all, because their wages were being subsidised by tax and the printing of money. Being unprofitable is not some minor debating point. Enormous numbers of people in the UK were being paid to uselessly dig holes in the ground. There was no purpose to this. In the absence of subsidies, nobody would have wanted the rocks that were being dug up. Other people in other countries were doing it better.
And it wasn't just mining. At the time Thatcher came to power the British state also owned shipyards, steel works, a furniture removal company and the Gleneagles Hotel ..... just to name a few.
None of this made any sense. It had happened because the post-war governments believed full employment mattered more than inflation. The result was openly Marxist trade unions realised a weak government with an addiction to money printing could be turned into an ATM via nationally organised strikes. By the 1970's the UK was a basket case. It was suffering electricity blackouts, trash was piling up on the streets uncollected, railways didn't work, even emergency services and hospitals were striking. The country was one of the poorest in Europe and being called "ungovernable". The strikes were wildly unpopular with over 80% disapproval ratings of the strikers being common.
There was no way these industries were ever going to be world-beating titans ever again.
Thatcher was elected to fix this state of affairs, and she did, by making the painful choice to take away the subsidies and start targeting inflation instead of employment.
By the time she left the UK was a stable and prosperous first world nation once again.
