At least one lawsuit is being threatened if the Legislature does not make major revisions in the way the state pays for public education. A public policy expert who has often advised the legisalture has come up with a new way to do that. Doctor Ed Robb’s plan ends the heavy reliance on the local property tax. It also calls for a change in state tax structure to have the state shoulder a greater role in paying for elmentary and secondary education. Robb says its a one-for-one swap of revenue form the local level to revenue generated by the state. He hopes to put his plan before legislators this fall.
