Whose equity are those judges talking about {"New Jersey Defines School Equity," editorial, June 15}? Judges have now joined the wild panoply of tinkerers proposing swift, efficient solutions to the problems besetting troubled public schools. The nation's taxpayers had better brace themselves for another attack on their pocketbooks.

The judges' solution, as all others, will require large infusions of money. The governor of New Jersey estimates it will take $440 million or more to achieve the court-mandated equity. Apparently it is of no concern to the courts where the money for mandating this equity will come from, but it will certainly concern the taxpayers of the states on whom this solution will be inflicted.

Experience leaves no doubt that throwing money at problems breeds bureaucracies. The amount of money New Jersey needs for the mandated equity will breed a huge bureaucracy because not only will the schools have to be rebuilt, reorganized and staffed but the state's revenue will have to be restructured. By the time all of the studies are done, committees convened, contracts let and control agencies put in place, the money trickling down to the schools may not be enough to achieve the court's good intentions or the improvements desperately needed.

This is not to say that the disadvantaged public schools must not be helped and improved, for they surely must be. Innovative, even radical, ways must be found (competition comes to mind), but they must also be tempered with common sense and fiscal restraint. A solution whose implementation threatens economic turmoil in a state government can only further harm an already troubled public school system. The imbalance in Virginia makes that state vulnerable to this approach and the troubles that come with it. In this time of economic uncertainty and declining government revenues, we need solutions that cost less, not more. AL CARRIER Alexandria
