OMG. It really is like talking to a wall isn't it? If only life could be simplified to a simple one liner.
Look, what do you mean by financial crisis?
If you mean the budget deficit then yes, that is virtually ALL Labour's fault. They inherited a balanced budget. It was balanced whilst they stuck to Tory spending plans, then it came off the rails when Gordon Brown decided he knew better. Yes, at the end, the deficit went up because of the banking crisis but this will turn us a profit in the long run so is less of a concern than the structural deficit. That's all on New Labour. Now perhaps the Tories would have done the same thing. Let's assume they did. If they had, you'd be screaming from the rafters that it was their fault wouldn't you?
Labour were in charge. They are responsible. FACT.
Did they cause the banking crisis? Not directly no. The banks did that. BUT and its a big BUT were Labour responsible? Yes, they share that responsibility, since they were only able to do that under a purposely lax Labour policy designed to woo financial companies to the UK. In fact, Gordo thought he was so clever that he preached his mantra to other more cautious nations like France & Germany.
It's like this, if my child at school today punches another child, is it my fault? No. Am I responsible. Yes.
