She gets a lot of heat, but much of what she done was for the long term good. She had more balls then any leader I can think of.
The town I live was a mining town. We had 3 pits. During the late 80's early 90's she shut them all down. Effectively she put most of the men in my town out of a job. It wasn't just my town ofc, she effectively ended the UK coal mining industry.
She is / was hated by the working class.
