I hate how I feel a hell of a lot smarter than most of the students and 1 or 2 teachers yet I know I'm not so great. The fact that no one thinks ahead at all. And for some reason I feel like I should be praised but I haven't anything expect what I'm supposed to do because no one in my school cares about others and they even make fun of me for being serious most of the time. 
Can somebody explain this to me because I've been thinking about this for a long time but I don't get why I'm feeling like this and it's really bugging me. 
To answer this question, lots of people make fun of others for being so serious at times because they themselves are not. Mind you, it's okay to be serious as the world needs more people to be serious, but to be overly serious all the time can be somewhat detrimental to your social development. It's good, almost necessary, to be silly once in a while. Laughter & downright childishness is important for keeping one sane. Joking around with friends, making fun of not only other people but yourself too is very healthy. When you don't do these things, a lot of times you can be picked on as you are seen as the "odd one out" and they are usually easy targets.
However, don't feel bad, because you can get made fun of for any number of things. If no one in your school cares about others, then simply don't care about them.
I know I'm not missing out on anything but how the heck do I stop people from making fun of me. I try not to react and ignore them but they just keep doing it.
Sadly, you don't stop people from making fun of you. It's a part of life, and always will be even when you're grown up. What makes you, well you, is how you react to it and how you deal with it. As I said in the above paragraph, it's very healthy to be able to laugh at yourself and to have a good sense of humor. If I found someone's insult of me funny, I laughed. If I didn't, I ignored it. The only problem you really have is when it gets physical, and you could get physically hurt. A wise man once said, "Sticks and stones may break my bones, but names will never hurt me!"
Is that what happened?
Yep, that's what happened. Those emergency exits were just regular exits.
Huh.
It seems to me this is one of those chicken-or-egg situations. Even though corporations do tend to shake people down for profits, people also cost any public service a great deal (e.g. their "I pay goddamn taxes so I'm entitled to treat this place the way I want" or something).
My father, an MTA bus driver, tells me that fares paid by customers aren't enough for the MTA to pay for their costs, so they also receive subsidies from the state and federal government. I don't know if that's relevant in any way, though.
Oh, I'm not disputing that people aren't at fault too. Like with the garbage thing, some people are simply inconsiderate and act like they are owed something in life for all their hardships. It's one of the prices you pay for living in a big city with so many diverse cultures.
As for fares & subsidies thing, it's not that relevant, however something has to change before your low income worker cannot afford a monthly MetroCard anymore.
