I may be wrong, but I believe that Margaret Thatcher would have expected celebrations of her death. She was certainly a narcissist, but she wasn't not self-aware. She may have even found the jubilation amusing to a certain degree.
The response from her apologists to said jubilation is that it affirms that Thatcher "won". Well, she definitely was victorious in numerous ways. She succeeded in destroying thousands of lives in systematically dismantling Britain's industrial base. She privatised basic public utilities, resulting in the parasitic corporate extortion that impacts us (particularly the thousands of impoverished elderly people killed by fuel poverty every year) to this day. She succeeded in aiding and abetting thousands of cases of murder, rape, torture and political suppression by the totalitarian and dictatorial regimes she supported across the world. Her Section 28 legislation ingrained homophobic hatred which remains, albeit in a waning state, to this day.
I could go on about her triumphs.
The original title of Thatcher's autobiography was Undefeated. Her most profound, undying victory is her hegemonic ideological monopoly of the UK's political establishment. She described Tony Blair, the self-described Son of Thatcher, and his transformation of the Labour Party into adhering to a rigid and opportunistic neoliberal administration, which implemented privatisation and financial deregulations nor she or John Major managed to, as among her proudest achievements. And Tony Blair did her proud her this week, in his attack on Ed Miliband's leadership for not accepting the Cameron coalition government's brutal welfare cuts, or tabloid propaganda rhetoric about "benefit scroungers", with sufficient uniformity. Iain Duncan Smith, the main technocratic architect of economic assault on the poor and vulnerable like the bedroom tax, has described Thatcher as the reason he entered politics.
Thatcher is not dead. She lived in pitiful and frail half-death for the remaining years of her life, but her presence was not necessary. She lives on as the almost holographic iconography of the increasingly malignant neoliberalism that pervades our society and lives. The neoliberal policies that are being imposed in the present are even more brutal and transformational than anything she managed, but they are in her spirit and within the foundations she set. The likes of Cameron, Blair and IDS are merely her vessels and minions.
Despite being literally dead, Thatcher is the closest thing Britain has to any of the dictators she supported. And similar to the Eternal Presidency of deceased Kim Il-Sung in North Korea, she is the figurehead of the dominating ideology of Thatcherism.
We only have the right to celebrate when we figuratively impale the stake through her undead black heart.
