Regards your 2nd paragraph, the impact of Brexit being greater than the loss to the economy from e.g. COVID, I would say is very debatable. The 2nd part about Truss is just complete nonsense, pure and simple. It's not even certain that the bond market crash was actually her fault, but even if it was, the impact in the scheme of things is trivial at most. Inflation rates were high and rising anway. World-wide inflation rates were shooting up, and yes if we accept that Truss messed up then she made it marginally worse. But to say that her actions had a bigger impact on the economy than COVID is just incorrect. All too easy for critics to blame her when in fact there were far bigger forces at play.
