The Green Party has as part of its platform the support of the progressive tax system. The logic behind it is that the progressive tax is based on need. In other words, you need all of the first $20,000 you make. You need a lot less of the last $1 million of the $5 million you make, if you're fortunate enough to make that much.
I am a big believer in the principles of Ivan Pavlov. Pavlov did experiments on mice and dogs that showed that you can influence behavior based on what you punish and reward. The progressive tax system punishes success. In fact, Ronald Reagan, when he first became an actor, got a first hand taste of its corrosive nature. When he was first an actor, many of his colleagues recommended that he only make two movies a year. That's because by making a third he'd wind up in a higher tax bracket and actually take home less.
The progressive tax system is an incentive to make less because the more you make the less of that you keep. We want to encourage everyone to maximize their income and the progressive tax system does the opposite.
