Thatcher did a lot for this country. Unfortunately all the good things she did have been forgotten and then "taken over" by the Blair years. The "prosperity" that we have all enjoyed with billions being thrown at the NHS and Education by NuLabour would not have been there had it not been for her legacy. That Blair, Brown and co have in fact squandered that legacy is not Thatcher's fault. They were like kids who, on reaching 18, discovered that their trust fund was no longer managed for them but they could do what they liked. That's why we are now heading toward bankruptcy.
You and I may not see any benefit from the billions spent by Labour over the last ten years on Schools, NHS etc but believe you me there are an awful lot of middle and senior managers in those and other sectors who are rubbing their fat little hands with glee at the size of their pay packets, bonuses etc.
Essentially Thatcher + Lawson provided the sound financial base on which, despite problems with the ERM, Major was able to build on and this shower have spent it on rubbish.
