I hold the opposite opinion, there should be no compulsory taxation, when you look it straight in the face, it's a form of partial slavery.
Also, the higher the income the lower the tax should be. In a free economy, where each person decides how to allocate their money, the people providing the most value to other people will be earing the most income. This means they are benefitting other people (society) more than those with a low income. Therefore this behavior, providing value to other people, should be encouraged with lower taxation, rather than discouraged by higher tax rates.
In addition, these high earners are generally business owners who are providing work for other people and creating value for everyone in the society by manufacturing or creating new products. If they have more money to work with, they can provide even more opportunity and value. These people are the true pillars of a productive and thriving society and should be treated with utmost respect and admiration for the incalculable value that they bring to our lives.
Without these people innovating and building, the world would be stuck in a perpetual dark age.
