I still find it hard to understand why people hate Thatcher so much.
I can give you my reasons.
It was her utterly inexplicable and hubristic policy to hold a strong Pound at or above $2.40, by maintaining interest rates above 18%, and keeping it up for more than two years. If you ran a manufacturing business, as I did at the time, your domestic customers weren't going to invest in new plant at those rates, and you were priced right out of foreign markets. I believe it's this that did more damage than anything else to the UK manufacturing base.
Worse, the almost overnight transition from record low to record high interest rates devastated the housing market. My monthly mortgage payments more than doubled over three months, and a year later people were just walking away from their under-water properties.
Everyone remembers the miners and privatization, nobody seems to remember the depression.
