College Education? Why?

Why is a college degree required for so many occupations? College does not make you a better worker, college does not make you a more honest employee, and I can even say that college does not make you smarter. Don't get me wrong; I'm all for being educated. The problem is, nowadays education isn't about being educated. It's about getting letters and pieces of paper and forms saying that you've been there and you've done that.
I'm going to college to be a teacher, but I already know that I could make a good teacher as I am now. In fact, I would make a better teacher than half of the teachers already out there. I have to take education classes, and I'm sad to say it, but most of the people aspiring to be teachers are really idiotic girls who just think little kids are so gosh darn cute! Here are a couple of direct quotes from my fellow classmates: "Does air take up space? I don't think it does" and "Peanutts? Aren't those those things that elephants eat?" These are the people who will educate the future generations, but I can't be a teacher yet because I don't have a little piece of paper to state that I'm "certified". Well, what does it take to be certified? Does it take lots of hard work, studying, and learning? Not necessarily. I could party every night and plagerize and cheat my way through all of my classes, as long as I get the grade in the end. That's all that matters, right? That's the way our society is, anyway. I don't agree with it. Why does someone need a piece of paper to get the job? As far as I'm concerned, that paper means nothing. It doesn't mean that I'm smart, it doesn't mean that I'm honest, and it doesn't mean that I'm a good teacher. It means I paid lots of money and wasted lots of time in order to be deemed "certified" when I was already qualified before I even stepped foot on a college campus.
