How are you sure your suburb is not getting subsidies from the inner core?

Because the county and city government budgets are public. We get no direct money from the nearest urban core and the only method of transfer would be through the state. We get very little of our yearly revenue through the state general fund, and we pay enough income(and other) tax to completely offset it.

We're self-sustaining primarily through property taxes and have been that way for more than a century.

You're not wrong, but your comments fall on deaf ears.

From the tone of other commenters here, I sense a malicious undercurrent intent on extinguishing rural ways of life - any excuse will suffice.

Then I don't see why you're worrying for government subsidies to be removed from your neighborhoods. I'm sure that paying for the water, road and electricity infrastructure is accounted in your numbers and you won't need anyone else paying for them.
