Income Tax

According to propaganda, income taxation taxes the rich. Then why are the rich so demanding to tax themselves by increasing the tax rate and even, like recently in Washington State, spend millions in trying to establish a state income tax ?  
Why are so many people who are staunchly opposed to income taxes clearly much, much lower on the income scale?
Washington State does not have an income tax, but plenty of multi-millionaires who want one. Amongst them: Bill Gates Sr. who spent millions of Dollars of his own money to put a proposal to enact it on the ballot.
Although, the word "income tax" was judiciously avoided, the measure was soundly rejected by the unwashed masses.
Actually, the original title of the measure is truly something to behold:
"An Act Relating To Education, Health Care And Fiscal Reform" !

That mouthful was successfully challenged by Tim Eyman, who had some tax cutting initiatives of his own on the ballot.

In the end, the measure lost by 65% to 35 %.

Perhaps Washingtonians know the truth: Income taxes are a tax on labor, not on wealth. Further, they delegate the burden of laying the tax on the taxpayers themselves. In other words (to the taxpayer): "You do your own bookkeeping according to our arbitrary rules, then YOU figure out what you should pay and send us a check. Then, if we should find something that we don't like in your calculations, we can take your property or put you in prison."

Sooo much better than having to send out tax statements and having them challenged by taxpayers !
