IMHO Her main "achievement" was to change the attitude of the nation from a society ( to quote her "there is no such thing as society") where community mattered to one where being an ambitious self-centred individual is not only acceptable but praised no matter who gets hurt or marginalised in the process! We are left with a nation that is growing steadily more money motivated and ruthless. Being suportive to others without expecting anything in return appears to be getting more and more rare and those who do are often ridiculed and looked upon as fools who are setting themselves up as "suckers" to be taken advantage of.
