"BadgersPaws, the deficit was, as you say, £40bn before the crisis and is now £150bn. That has been caused by a precipitous drop in tax revenues and by the continued need to lend money to the banks."
Yes the deficit is due to the drop in tax revenues but no it's not due to lending to banks, as the ONS says the figures are "public sector net debt (excluding financial interventions)"
"it was caused by tax revenues tanking as the economy went into a recession that was sparked by bank failure."
Yes.
But we were in a bad shape anyway during what should have been the good years.
But the point is that to say "we have thus had to cut services to find the money to pay for the funding" is untrue. That huge deficit isn't due to us borrowing money to bail out the banks, it's just due to us overspending. We started off overspending so hitting a time of trouble will then just make the monumentally worse, which is exactly what has happened.
Blaming the bankers for the recession is fair.
Blaming them for the size of the deficit is unfair as it was big already and Government spending was already outstripping it's income.
Even if the bank crash hadn't have happened we'd have had to have tackled that deficit eventually. Recessions do happen, it's part of the cycle, and the deficit was unsustainable before we went into this most recent one.
