I think this is quite a good article on why she was devisive:
It’s interesting, but this one in my opinion is far better:
It tells you precisely why her policies failed.
Not sure about this phrase:
The question is whether any of it was sustainable. Now, there is a growing and dismaying recognition that too much growth in the past 30 years has been built on an unsustainable credit, banking and property bubble and that Britain’s true long-run growth rate has fallen to around 2%.
There was a property/credit bubble in the late 80s, which was allowed to collapse, but apart from that UK debt (both private and public) was relatively low up until about 10 years ago. Things obviously went wrong over the last 10 years but, as I’ve said before, you can’t blame Thatcher if a different set of people screw things up over a decade after she left office. Economies are dynamic things and constantly need adjusting – if her successors failed to see what was going wrong and stuck to the policies that were designed for the 80s then it’s more their fault than hers.
