So just to be clear to my American readers, this may seem spiteful or even malicious. You might think Thatcher was just a politician and didn't deserve to die in unspeakable agony.
Well, let me give you some context here.
I'm Scottish, born and raised. Thatcher trialled a new system of national tax in the UK; specifically in Scotland. It was a flat-rate tax, called the Poll Tax. Flat-rate here means that everybody pays the same percentage of tax from their income. Everybody.
