It's very easy to say things in hindsight, but I don't think anyone had a clue what a government under Margaret Thatcher would bring. They didn't widely advertise that they were going to take the neo-liberal path and dump entire communities on the scrap heap, for instance.
Which, indeed, brings us back to spin: for instance, think of how privatisation of utilities was spun to the public: 'more choice'.
Something that seemed comparatively minor at the time – the changes to Sunday trading laws – were spun as removing silly things such as being able to buy porn on a Sunday but not a
Bible; not that big retail wanted to be able to open more and more, as we moved from a manufacturing base to an economy based primarily on the service sectors (including retail). Think of how the cult of home ownership was spun too.
