Labour's economic policies regarding banking regulation had support from both sides of the house.
Running a government surplus large enough to nationalise investment banks on the off chance that it's required would have been foolish. There's no such thing as "past our means" - the fact we were still able to borrow the funds and service the repayments means it was within our means.
Labour did a lot wrong, but they didn't cause a recession. The Tories love to trot out the line that government can tank an economy which is intrinsically linked to global conditions. But when asked to explain why Osborne misses his own self-made targets then suddenly the economy is an unwieldy beast that is hard to tame.
England was part of that global economy that Labour and Labourites like to forget entirely. It's almost as if London and the banking that happened here had no bearing on the global economy at all therefore policies under Labour had no effect. THe recession happened thus it must have happened here.
It's not at all possible that if England hadn't had such a disaster and the banks were stronger amongst general spending in the UK that the recession may not have happened at all? The reality is, not likely, the absolutely likely scenario is the recession could have been FAR less bad for the UK and probably the world to some degree if not for Labour's horrific government running.
People like to pretend the recession caused all the problems here and that is the end of it. No Labours horrific overspending on some truly awful public works meant we were spending billions on things that had no long term pay back.
Spending 2billion on a train that brings business to somewhere in the country(not arguing HS2 will, just a the concept) can bring future tax income to surpass the spending on it. Billions on a ID scheme which gets canned because it's both ineffective, no one wants it and it doesn't work has NO long term jobs to bring, no tax income, not even a service. If the money spent on an ID scheme absolutely no one wanted was spent on something else, we would have been in a better state. Billions on late NHS systems that were eventually cancelled and basically thrown away, same deal. Had the system worked and been handled competently then the NHS could have been running better now, giving better service to patients and quicker/easier IT for the staff. Instead that money was thrown away.
Also don't forget the drastic expansion of jobs paid out of tax rather than jobs paying into tax. The government under Labour shrunk everywhere that mattered, wasted money on things that had no long term benefit for the country at all, drastically increased red tape and backroom staff in the NHS. Anyone remotely serious would tell you it was a joke and half the backroom staff could have gone. But increase spending, throw people, change stats so they look better and temporarily reduce unemployment and woo, everyone wins.
You then get into the budget game, a LOT of departments(not Labours fault, just a world issue) is that department heads want to get the same or increased budgets because budgets are seen as power. The guy with the 5mil budget for his department is more important than the guy with the 3mil budget. So people lie, cook stats and basically try and bump up their department 'needs' to stay 'powerful'. The NHS is a mess, largely Labour's fault.
All of this had a huge effect on how deep and how long the recession was and how long it will take to recover.
