Amy Hetzner notes the interesting paradox to the current situation:

Residents in more than half of Wisconsin school districts could have ended up paying more under an all-but-dead idea to raise sales taxes to provide $1.44 billion in property tax relief, a new study says.
Milwaukee residents, in particular, could have paid $1 more in sales taxes for every 77 cents their property taxes were reduced if the plan had been in effect in 2003, claims a Wisconsin Taxpayers Alliance report released Friday. In all, the study found 223 school districts containing 56% of the state’s public school enrollment would pay more in sales taxes than they would save in property taxes.
The study found that taxpayers in the Madison Metropolitan School District could get $1.20 in property tax relief for every new sales tax dollar.
“What this tells me is that when I see districts like Madison and Middleton in our area and Menomonee Falls or Wauwatosa in the Milwaukee area with positive returns of $1.20 per $1 sales tax or $1.30 or $1.40, that suggest a pattern going on,” Berry said.
