I can't speak for the others on this site, but I understand that debt is not bad, and can be used constructively.
And - yes it would have been great if the stimulation came - in the form of infrastructure buildup. - Roads. - the Redcliffe railway and others. - Darwin housing - a clean power station!
What we got was $900 handouts, overpriced buildings (BER) in the form of cafeterias (though some ok), insulation scheme with little benefit to Aussie infrastructure (and a killer to valid insulation companies), green loans (fail), etc.
Debt is good - if used properly. If I borrow money to make money (like banks, margin loans, etc) - good. If I borrow a bucketload of money to buy a really cool new car - then I'm an idiot.
