How can some states manage their budgets when the federal government fails to do so? Good question. And one that Oklahoma state Treasurer Ken Miller says he was asked this week at the Conference on Budget and Fiscal Coordination in American Countries, held in Mexico. Miller, a Republican, was invited to “discuss best practices for efficient operation of state government.” The trip was not made at state expense. A treasurer’s office press release said Miller’s advice was to build a revenue structure that’s diversified, recurring, stable and “profit-friendly.” Good counsel. As for the question posed above, Miller said the state’s fiscal condition relative to the federal government’s “is due in large part to a conservative philosophy, a restrictive constitution, bipartisan political cooperation and a thriving energy industry.” Must Washington travel to Mexico to learn how to get its house in order?
