I seriously doubt that you pay tax.
Unless you're some form of master child entrepreneur. I doubt you pay tax or anything above a couple hundred dollars that you could easily claim back. Also don't pull some bullshit "but I pay GST lwol" argument, either.
I think scuba_steve here has the right idea. Liberal, if in power, would have used a stimulus package to attempt to avert any short-term recession basically due to pressure from external + internal forces.
On a two party preferred system, I'd vote Labour. Mainly because they're going to put in a Broadband Network that'll hopefully fix up the shitty net we have at the moment. They'll also keep their relatively socialist policy of paying for education, so I can do good with that over the next 4 years before election swings around again. Will reassess political priorities afterwards.
