I am in the most favorable of all tax categories, I am self employed. That means that I can deduct virtually all my expenses associated with conducting and generating business. The ordinary poor person is in a surprisingly unfavorable tax position for several reason.
First, they tend to have jobs that file W-2s so that their income is fully reported even on part-time jobs. Second, I have an accountant who keeps me posted on tax changes. I know he is valuable and he prepares my taxes. Third, I keep meticulous accounting records.
The most significant reasons that poor people pay more taxes than I is because there are heavy sales taxes on liquor, cigarettes and the lottery is a tax itself.
I can't avoid the 10% sales tax that we all pay in San Francisco. But my light consumption of alcohol and abstinence from cigarettes and the lottery assure me that I will not be paying the exorbitant taxes on those items.
There are additional reason that I don't pay as much taxes as the ordinary poor person. One, I live in the central city and have very low gas mileage and a car with good gas mileage. That is not usually true for the ordinary poor person. Lastly, I am a simple liver so I have cars that are old. New cars and frequent automobile purchases on credit generate taxes I don't pay.
I repeat: the ordinary poor person pays more in taxes that I do.
