standards are not maintained, then quality will decrease.
Standards are required when there is no competition. When competition is introduced, those that do better with less advance, and those that don't diminish.
FURTHER, I would suggest that standards tend to stagnate over time, or worse become increasingly useless as additional standards are placed (and then stagnate) in attempts to increase quality, having the exact opposite effect.
I work in education, and the education model we have, and are trying to maintain, is industrial era format, with Factory Schools building robot workers. The problem is, we aren't there anymore, and the model has to change. We don't have to keep inventing wheels to educate our kids more effectively. We just need the opportunity to change the system via Competition, where most end up better off.
