No-one got bailed out, that is actually part of the problem in the UK. The US cleverly bailed out key firms, let the really troubled ones fail, and had no disruption to growth from financial disorder after 2010.

The UK acquired the same firms, went full ham on regulation, and there has been massive corporate deleveraging because most banks don't really do corporate lending anymore.

However, any firm that did have existing finance relationships was grandfathered in. Rates fell, and so these old inefficient firms have largely survived hoarding both labour and finance (the UK also has a disproportionate number of very unproductive family-owned firms).

The UK is the textbook case of finding the absolute worst thing to do at the worst time. I wouldn't say the issue is necessarily bailouts but regulators (and particularly the BoE) not understanding that the financial cycle plays a role, that bureaucrats shouldn't be intervening into management decisions by banks, that fiddling the price of money has trade-offs...I agree, but the decision to bailout is a product of beliefs that continued to damage after 2010 (and this was far less the case in the US, the bubble in tech stocks/SPACs/etc. demonstrates that the system is still alive...this didn't happen in the UK).
