The problem is that no one is naive enough to believe they'll somehow lower any existing taxes (either sales or property) with the introduction of an income tax. They'll keep them all, and try and introduce some new program that helps a specific demographic. From what I see, this usually ends up with money moving between pockets with a bureaucracy taking its cut along the way. I try not to be overly political, but I can't stand the idea of a strong, central planning government. Let's see a balanced, itemized budget. Even in the article they're just spitballing ideas with what they could do it an extra $140m.
