Mr. Joost is correct about a flat tax in that everyone would pay; unfortunately it would mean that the middle and lower income classes would pay more in taxes and the well-to-do would pay less. Perhaps those "occupy wall street" folks in front of city hall have a point.
And regarding local politics and the implication that everyone pays property taxes and has "skin" in the game; I assume he has overlooked the renters, indigent, and homeless.
As someone else commented, lets focus on Jacksonville's problems.
