Governments idea of cost is that when they want something and money isn't there, to tax the people some more. The idea of cutting cost never enters their mind. This is especially true when it comes to the school board. They even go so far as to try and lay down this guilt trip on the people if they don't get what they want.
Until people put their foot down and say no more, it will continue. And to all those that talk about SPLOST then research it and read about it. Local government get it in place then abuses the heck out of it. And ignorance allows them to do it. People's ignorance.
