For the past, let's say 100 years, the expectation for educational achievement for children coming through the local public school system has been slight. If you doubt my opinion, please tell me why the school buildings look so bad and the system won't even provide enough textbooks to teach fundamental science and math. As you read the editorial opinion offered this week in CityBusiness, it's easy to see we think the evidence is overwhelming. We've asked anyone on the school board who has failed to back Anthony Amato as superintendent to step down. The business community, including Mayor C. Ray Nagin, Gov. Kathleen Babineaux Blanco, the state Legislature and the Board of Elementary and Secondary Education all smell a rat.
