Genuinely not being nasty but you and shmmeee are deluded if you think the big Uk banks could’ve been allowed to fail. There would’ve runs on banks (see what happened to northern rock and Icelandic banks - small in the grand scheme of things in terms of Uk).
Have a look into fractional banking. The banks don’t hold everyone’s cash and there would’ve been a unravelling of the financial system, the economy and civil unrest before the government would’ve been able to get control of the situation.
Gordon brown, whilst a flawed character, is not some capitalist idiot. He wouldn’t have taken that decision lightly
The bigger issue, as mentioned previously, is nobody seemed to pay the price for the damage done…bit like China with Covid…the culprit(s) gets away with it and the rest of us pay the price
Either way, what’s done is done
