sorry, I'm on my phone and it's difficult to pluck this quote. The millage and bonds are two different things. I was pointing out another limitation that rural schools and those with a small sales tax base have.
When you get to your regular computer to respond, please note my comment also included info that sales tax is not part of regular school funding. It has been part of special funding in certain circumstances, ref. the MAPS tax in the OKC area. Also, millage and bonds are related in that the millage assessment for a school district directly determines the amount of bonding capacity for construction and capital expenditures.
