Trying to have a discussion about Thatcher in the modern culture war era is futile. Either right wing grifters tell you she was good and you believe it or left wing grifters tell you she was bad and you believe it.

The fact is the British economy WAS in complete stagnation. The Unions WERE overly powerful (they routinely shut down the entire economy for days over minor labor disputes) but equally that Thatcher's policies, even putting all morality aside, were retarded. She had the option of investing in Coal mining and Steel forging to make Britain the workshop of the world again, instead she simply privatized them, they closed due to unprofitability, and the economy became shifting monopoly money around. Britain became and has stayed a nation with no actual product or tangible good. It's just vast tracks of economically impoverished areas artificially boosted to an average standard of living by fake money being shifted around in London.

So literally everyone is right, the left wing grifters and the right wing grifters. Maggie was a retarded cunt who destroyed the British industry and the industry was a wreck that needed investment, not destruction.
Every problem is a nail when you have a sledgehammer.
