Alright kiddo, so a fair tax town is a place where people decide to create a system where everyone pays taxes based on what they can afford. This way, everyone pays their fair share and no one gets unfairly burdened with too much taxes or gets away with not paying enough.
It's like when you're having a party and you want everyone to bring a dish. You don't want one person to bring all the food or for someone to come empty-handed. So, you decide that each person should bring something that matches what they can afford. This way, everyone contributes equally and no one feels left out or overwhelmed.
In the same way, a fair tax town is making sure that everyone in the town contributes to the community based on their income, so that the town can have enough money to provide everyone with good things like roads, schools, parks, and other important services.
Does that make sense, kiddo?
