You really think that taxing the deck out of the wealthier would of helped to balance the books, and fuel a recovery? Labour's forecasts and predictions on the economy in this parliament have been woeful, to say the least. When you need investment, you don't go full on anti business. With a fragile global economic recovery we are competing with other companies for investment in this country, if that spanner Ed balls gets into no.11 I fear for the economy.
Also the gap between the wealthiest and the least wealthy in society accelerated under the last labour government, so not sure why you think they will address that in any significant way.
I just remember too many vanity projects under the last government, and how they spunked record tax incomes, leaving the cupboard bare. It's basic economics that you put money away in the good times, for the rainy days, they should have been running a healthy surplus prior to the recession, it was reckless, and reeked of stroking the egos of new labour, rather than doing what was right for Britain. Public spending increased sharply in the last two years of labour 2008-2010 as we were at the height of the financial crisis. The opportunity was there to address national debt was there in the good times, but wasn't taken.
