If Truss and Kwarteng had instead come out with a good budget which would improve the lives of 99% of citizens but at the expense of the rent-seeking hoarders of capital I think the same thing would have happened.

That is very very easy to say, especially when they didn’t. Other budgets were not unfunded messes which sought to grease their mates’ pockets (so much). They thought they could fuck about and do what they wanted.
