Thatcher left office in the early 90's, right? I remember it was sometime around the 2008 financial crash that the pound just started tanking and never recovered. Every subsequent crisis, the pound falls more vs the dollar/euro and never really recovers. At least that's how it feels to me as someone that gets paid in pounds. Every year I feel like my money goes less and less far.
