Although I agree with you if any tax comes to fruit ,which they will, it will  not be a sales tax but an income tax. It is the easiest and most effective of the taxes to implement and can be increased at the legislators whim.  Like homes owners are held hostage with having to pay property taxes or they will loose their homes the people who need to earn an income/wage to support themselves and their families will be held hostage of having to pay an income tax and if they would not pay they would face time behind bars. 
Legalized extortion is all it is. Theft by any other name is still theft.
