She left office 30 years ago. I really don't think she's to blame for the UKs current economic mess and every other financial, political, humanitarian disaster she's apparently personally responsible for. The Euro is rapidly turning into the clusterfuck she predicted and local manufacturing is buggered by super cheap Asian imports more than anything else.
It's always been trendy to Hate Thatcher, especially by people who weren't even born when her evil junta was running the country. I also fear the great unwashed will use her funeral as an excuse for violence.
