The Mayor's speech at the Chamber breakfast had a few interesting points, but this one
".... the property tax, which is the most regressive tax."
Umm, no. The sales tax is by far the most regressive because poor folks pay a far higher portion of their income into it. Conversely property tax is based upon the assessed value of property. The owner, if she/he cannot afford the taxes, usually has the option of selling. That doesn't hold true when you are paying sales tax on a jug of laundry soap.
Property taxes can, indeed, be unkind to those who lose income or whose properties increase in value faster than inflation, but that is hardly considered regressive taxation.
That said, the mayor's larger point was about the meals and lodging tax. I might be the only chef in town who says "go ahead and raise it", but 2% of a typical bill at a restaurant isn't going to bankrupt anybody.
And consumers always have the option of learning how to cook their own groceries - tax free.
