with the homerule charter that might be hard
There are already people screaming about how it's regressive and hurts lower-income earners proportionately more than high-income earners.
They're going to have to agree to a few things to get this passed, I think:
1. Cap city sales taxes so people aren't paying 15% in some places.
2. Make sure the necessities aren't taxed (like food). Or at least not taxed the same way.
3. Figure out how to raise property taxes or at least have some sort of failsafe should everyone suddenly realize they can just not buy things and not pay taxes. Dems will throw a fit over potential budget shortfalls if higher education/health care remain the only areas available for cutting.
