How long will it take the Coalition to restore Australia's economy after this Labor experiment has ruined it?

It took John Howard and Peter Costello and some sensible government about 7 years to put Australia's economy back together after that last great Labor experiment of Whitlam, Hawke and the wizard Keating had made the country an international fiscal laughing stock. How long will it take the Liberals and Nationals to correct this current spillage of our money, to again send the country stone broke? Why didn't we learn last time we gave the Labor/Union movement a key to the country's bank account?
