Can't agree completely. Part of the job of a teacher is to inspire.
Teaching has changed since I was in school. Of course part of that could be because I attended a small rural school and I now work in a larger city school, plus there is more technology available (computers were just beginning to be "common"). I see things that I didn't learn until in High school being taught to 6th, 7th & 8th graders (mostly math) while things I learned in Junior High (mostly English/Lang. Arts) isn't taught to them anymore.
As a teacher I could stand on my head and I'd still have students that:
a) just want to disagree with everything (The sky is not blue it's _____)
b) is just doing time until they are 17 and can legally quit
c) spend all night playing video games/running the streets and are too sleepy during school hours to stay awake, much less learn
Not all students are this way, but a public school has to take all kids (private schools can chose not to "babysit" problem students and devote their time and attention to those that want to be there)
As a parent, I try to make my kids take responsibility for their own actions. I send them to bed at a reasonable time, ask about homework and help if asked, etc. but I cannot go to their school and make him pull that homework I saw him do out of his binder, stop passing notes/talking, etc. (The school district I work in doesn't take out-of-district kids and I'm not changing districts just for the few years my kids are in school.) The student has to realize that he/she has to work to make their life the way they want it, be it the way they dress, act, or whatever. The old adage about "You can lead a horse to water, but you can't make him drink" applies.
Back to the original topic, I don't like the saggy pants, holes in jeans (but you can buy clothes that are distressed and those holes appear after a few washings - that's one reason why when I pay good money for clothes, I want them to look new and not old; old will come with time) and b**bs about to fall out of spaghetti strap tank tops that some of these kids think are acceptable to wear in public. Oh and don't forget the I-just-got-out-bed look of flannel pj bottoms and slippers for shoes. The majority of students make good clothing decisions and some make such cute clothing decisions that I wish I still had my slim teenage body back so I could dress like that too.

OK, I'll get off my soapbox now.
