You mean people like Gordon brown that deregulated the industry? That charlatan. You really have no idea about banking do you?
Just because something is legal, it doesn’t make it right. The greed of the banks caused the recession. The recession caused austerity and austerity has fucked society. You could even say austerity is what gave us Brexit.
Life is what you make it , some have the drive and are prepared to risk everything to succeed, some like to be supported by the state.
Theres plenty of folk between those two extremes , some have strong views either way , deal with it.
Having the drive to succeed does not mean you get to trample on those below you.
