Debt and deficit. The Rudd government inherited a massive $90 billion financial firewall when it came to office, via a federal budget surplus, the Future Fund and two infrastructure funds. In two years the budget has gone from $20 billion in surplus to $58 billion in deficit. Net federal debt has gone from zero to a projection of between $130 billion and $180 billion. It took the previous government 10 years to dismantle the $96 billion debt mountain that it inherited. It took Rudd one year to build it back up again.
