The tax man gets you no matter what. Whether its through income tax or sales tax. Look at Tennesse for instance. The residents of Tennessee did not want income taxation to the point they modified their state constitution to essentially ban them. But they did this knowing that there will always be climbing sale taxes. They have a state wide 7% sales tax, as well as local districts can impose their own sales taxes on top. While it may not show up directly in the bottom line, they always get you. Now one can argue that then said person just takes their money else where to spend it, where sale taxes are cheaper. Especially someone of a millionaire means that can freely travel when not dealing with their occupation. But that's a ability they have due to their income. Personally, myself being someone that does not have that means to travel freely like that. I would rather have a high sales tax, and have control over what portion of my money gets taxed by the purchases I decide to make or not make. Than be blanketed with someone that could live right across the street from me, earn the same amount as me, and gets taxed almost identically to me even though we have completely different spending habits. Right now I live in California where taxation is insane, I pine for the day I can move back East. As far as adapting the salary cap to taxation. It would become an absolute nightmare. Introducing numbers that have the ability to change depending on state representation and/or voting with numbers that already change every year in a currently complicated cap system. No thanks.
