@okie,
You do realize that part of the cost of "educating" a child includes construction, building maintenance and utilities, don't you?
During academic 2006-07, the city of Arlington, Massachusetts spent $100,000 heating school buildings. Arlington could begin to solve the problem by replacing their aluminum-framed windows or it could simply wait for global warming to eliminate the need for heat.
Local control? OK. Make the kids wear wool sweaters and dial down those thermostats to 62 degrees F.
