It is deeply ironic that capitalists have needed socialist ideas to save capitalism from itself, but you can't use this set of circumstances as some sort of simulation for how a socialist government would look in the UK, it just isn't at all the same.
I'm not essentially a Capitalist but the cynic in me suggests large scale cash injections are done to save the integrity of the stock market as much as a genuine need for people to pay bills. The stock market collapses and the mega rich go under. The global economy has been falsified for years. I really do not know how Socialism can be defined but I see it as an obligation to care for the vulnerable and that isn't necessarily valued in monetary terms.
