I have a uniform and I really don't mind it. It's not the most comfortable or attractive thing but its SO simple. You don't have to waste any time wondering what you're going to wear and what people will think about it. I also get to sleep much later because getting dressed is so simple.
I say it's a good thing. People want to express their individuality, but not everyone knows how to do it without offending someone or violating a school rule. When these kids get a job in the real-world, they won't be able to wear saggy pants and small pieces of clothing.
And, yeah, it takes out the extra stress of deciding what to wear.
