nah, not really. you can argue long and hard about how the industires affected should have done more to modernise, more to realise that rationalisation was inevitable, more to future proof their own industries. No one is saying that Arthur Scargill wasn't an idiot who doomed his own industry to a fight they couldn't win. The salient point though is, that for whatever problems the industries had, Thatcher's solutions were worse.
If she was a doctor, and you had a problem with an ingrown toenail, her solution would be to amputate at the ankle.
... and that's before you get onto the whole poltiical ideology and culture she helped advance in this country, the one we are living with today.
