I had actually hoped to see more UK hypesters post in here. I may not have lived through her premiership as prime minister, but growing up in the 90's I certainly reaped the benefits that she sowed. Of course, I acknowledge that times became very difficult during her tenure as the PM, my parents had to live through it, but honestly, it was what was needed, the country had been in the grip of trade unions for years, undermining the parliamentary democracy that we are governed under, and Thatcher took the "my way or the highway" approach. Yes, jobs were lost and in 1984 over £1 billion was lost from the GDP, but it stopped the strike epidemics that were seen in the 70's due to the legal privileges the trade unions gained under Labour.
Whilst I am against any further privatisation, much of what Thatcher did with it benefited the country, with the average person becoming richer, as well as GDP actually going up over 20%. She was very much an advocate of social mobility (being an example of it) something advocated by every British politician now.
She reinstated the UK's standing in the world. Obviously following the Suez Crisis, it became clear that the UK could no longer act as a superpower any longer, and the country began to go into decline, she reversed this, with her relationship with Ronal Reagan, taking a proactive stance in the Cold War, earning the moniker "Iron Lady" and did the unthinkable by telling a US President "not to go wobbly". She integrated the UK into the EU despite enormous opposition. Amongst countless other achievements.
Love her or hate her, following Michael Foot's "longest suicide note in history" manifesto for the 83 election and her own successes, she changed the UK to this day at home and abroad. Without her, we wouldn't have seen the 16 years of unbroken economic growth a much larger middle class and we wouldn't have the modern Labour party. People in the UK are better off now and it can be traced to her. So even if you view her as evil (for which people can very much be justified) she was very much a necessary evil.
