Those of us who were adults in the 70s, working and trying to run businesses have memories of what the 70s were like under Conservative Heath "the 3 day week" and then Labour Callaghan - Britain going cap in hand to the IMF for funds to bail us out - we were the Greece of the 70s. We were "the sick man of Europe", Jim Callaghan "crisis, what crisis?" millions of days lost through strikes, many of them wildcat, the "winter of discontent". Britain going down the toilet so fast with the Labour government completely impotent when it tried to do anything about it.
That is what brought Thatcher in - the need for tough decisions if Britain was not to sink into a morass of strikes and debt. So, yes, massive suffering via the mines, the shipyards etc. and of course there is ongoing hatred for the person who is seen as a destroyer by those who saw their livings destroyed. And misogyny too - the fact that a woman was tough enough to do what was absolutely necessary to rescue Britain from bankruptcy while the previous weak male PMs had presided over failure, didn't go down well.
As for the apparent "not interested in women's issues". It was clear why. She had the whole country to think about - the big picture. And if the economy goes down the tubes everyone, including women, suffer. A PM's job is to be PM for all - not any one class, sex or group.
She won't be seen as a feminist icon because she was not of the left. But she should be because she showed that women can succeed without special pleading, special status and tokenism.
