One legacy not yet touched on in this thread is the culture of individualism, or the consumer culture. Whether this was made by the prosperity that Britain enjoyed, or whether it was made by the religion of individual responsibilities that Thatcher believed in, there was a shift from the old conservative ideas of social responsibility (conservative includes both Tories and socialists), towards an emphasis on individual rights (consumer rights), which society (the seller) had to fulfill. That IMHO was the greatest legacy of Thatcherism, which is why her politics cannot adequately be described as Tory or conservative, for it was neither, but liberal.
