I've caught a couple of informative chats about what she was trying to do, and there are some informed articles in print.
I don't claim much understanding of the theories about growth. There seems little agreement, so they can't all be right. (Overridingly it's bad for the planet, but that's another matter).
There was a program on Radio4 in which economistas looked at what she did and why it wouldn't work . (EG, cutting taxes for the rich 'worked' for Thatcher but she cut highest tax from 70% to 40%. Now, 45 to 40 was never going to do much. There are parallels with what Reagan did too. It's probably on a podcast. Half an hour worth hearing. A walk on the Supply side.
Here it is but the link's not quite right:
As Truss was quick to point out, most of what she did was about the fuel cap, OK, plus some stuff for tax cuts. There was wailing that it wasn't funded. Well OK but neither were furlough payments. One will hopefully not recur in decades, the other will go on a few years. Is that the only difference?
It was monumentally stupid to do daft-looking things without any explanation, but what was disastruss was the "market" reaction, it seems to me, rather more than the measures themselves.
Question time last eve was mildly interesting. Stuart Rose was on, always worth a listen, and a savvy woman who's something like the editor of The Economist. At one point she said she was in violent agreement with Rose. I used to use that phrase in meetings. There was always someone who thought a fight was in the offing.
