A question, though: Why do people hate Thatcher so much? Several reasons, I guess. But a lot of the things which New Labour did after her were much more right-wing politically...
Could go into specific reasons, but I think a very pertinent fact is that, pre-Falklands, her opinion poll ratings were lower than Dubya's ever got, which is quite astonishing. Lowest in UK/US history, I think I'm right in saying.
As to what - vicious attacks on unions/miners/by extension whole communities, not alleviating effects of mass unemployment, sick divide and conquer tactics with respect to working class people, starting the cult of privatisation against reason, poll tax, reduction of social expenditure, and, more abstractly, denial of society and an excessive emphasis upon individual greed over community, opposition to everything good and beautiful.
Probably lots more stuff.
Maybe New Labour just were't as
good at being destructively right-wing as Thatcher.
