Thatcher
I had my teenage years through the 80's. I watched the UK change dramatically after the conservatives won the 1979 election. The country seemed initially to be in distress - the miners strike, rubbish piled in the streets, the poll tax riots. Then the boom. The opportunity to buy council houses, yuppies, banking and financial services just exploded. The country found a new place in the world and particularly after the Falklands War - we we're proud to be British.
Do we owe this tumultuous change to Margaret Thatcher? Mostly I think we do. I didn't like her politics but the country needed change and she had the unfortunate task of modernising a country that likes its traditions and its heritage.
Taking the miners as an example, what were the alternatives to close the mines that were unsustainable? You either closed and reformed the industry or you held the country back while you paid for something long past its sell-by date. I sympathised then and now with the miners who just wanted to work - and the communities that were decimated by the pit closures. It just wasn't an option to keep them open under government subsidies. That way of working had to go.
Jumping forward to the moment of Margaret Thatchers death. Whilst some were happy to see the back of her - a more philosophical point of view would be that at a moment in time she did what what we all understand as being necessary now with hindsight. I still don't like her, or her politics but where we are now as a country - a modern, progressive, tolerant and democratic country that other nations aspire to be like is what we have from that period in time.
