<p>Well, it comes back to scarcity. There’s only so many of the best of this, that, and the other thing, and those tend to end up going to those who put out the best work, the most work, or what-have-you. Even if it ends up being something as basic as ‘person that can catch more fish gets more food.’ The best are well-nourished; the worst starve. It’s not a fun time to be the worst.</p>
<p>An independent drive to do one’s best isn’t the same thing as competition. It’s important to emphasize that as well, since it’s equally important to human development and advancement. But competition is inherent in society. There’s always going to be a need to take out the trash, do the dishes, walk the dog, and so on. Some people want to do some jobs and avoid others. Odds are, the quantities won’t line up perfectly. So people compete for the more scarce, desirable job, and some simply won’t get it.</p>
<p>Given a finite quantity of anything, competition will erupt over who gets how much of the thing. Since resources are finite, it’s better to have a greater chance of getting what you want and need, by being bigger, faster, stronger, smarter, more adaptable… whatever it is that gives you a leg up on the others.</p>
<p>Let’s make this relevant. I want to go to a good college. The college can support and instruct a thousand new students every year. There’s more than a thousand potential new students in their senior year of high school in the world. The students need to somehow prove that they should be at that college. The college wants the best, most interesting students. It’s admirable to do one’s best. It’s more appealing, however, to be one of the best. The -most- able students make it into the college. It’s nice to have students that are good enough, but why take the good when you can have the great?</p>
<p>Since there’s a large amount of people who (probably) want at least some of the same things, it’s in their best interest to become accustomed to the idea of competition, so they’re ready to go after the rarer things in life. The most important, and most difficult part of competition, is becoming accustomed to losing gracefully and learning without panicking or becoming depressed. That’s where things go wrong, in my opinion. People are taught that it’s enough to do their best, and that doing their best will make them all right. Everyone loses sometimes, and it’s important to get used to the idea. Losing won’t always be deadly, hm?</p>
<p>Edit: props to futureoriented for hitting some of the same points I wanted to make.</p>
