Writing: summarize the following passage (Within 100 words) :
One unversed in such matters can have no notion of the many and tragic things that can happen to a chicken. It is born out of an egg, lives for a few weeks as a tiny fluffy thing such as you will see pictured on Easter cards, then becomes hideously naked, eats quantities of corn and meal bought by the sweat of your father's brow, gets diseases called pip, cholera, and other names, stands looking with stupid eyes at the sun, becomes sick and dies. A few hens and now and then a rooster, intended to serve God's mysterious ends, struggle through to maturity. The hens lay eggs out of which come other chickens and the dreadful cycle is thus made complete. It is all unbelievably complex. Most philosophers must have been raised on chicken farms. One hopes for so much from a chicken and is so dreadfully disillusioned. Small chickens, just setting out on the journey of life, look so bright and alert and they are in fact so dreadfully stupid. They are so much like people they mix one up in one's judgments of life. If disease does not kill them they wait until your expectations are thoroughly aroused and then walk under the wheels of a wagon - to go squashed and dead back to their maker. Vermin infest their youth, and fortunes must be spent for curative powders. In later life I have seen how a literature has been built up on the subject of fortunes to be made out of the raising of chickens, it is intended to be read by the gods who have just eaten of the tree of the knowledge of good and evil. It is a hopeful literature and declares that much may be done by simple ambitious people who own a few hens, do not be led astray by it. It was not written for you. Go hunt for gold on the frozen hills of Alaska, put your faith in the honesty of a politician, believe if you will that the world is daily growing better and that good will triumph over evil, but do not read and believe the literature that is written concerning the hen, it was not written for you.
谢谢了！

挺有趣的文章。

不了解养鸡的人很难想象一只鸡会遭遇多少灾难。鸡从蛋里孵出来，小小的，毛茸茸的活上两三个星期，和复活节贺卡上（的漂亮鸡雏）一个模样，然后变得光秃秃的非常难看，大吃你父亲满头大汗搬来的玉米和谷粉，得那些叫禽舌喉炎、禽霍乱之类的疾病，蠢蠢地站着看太阳，然后病死掉。少数几只母鸡偶尔再加只公鸡，为了服务于上帝神秘的目标，挣扎到成年。母鸡下蛋，然后孵出其它鸡来，完成这可悲可怜的循环。这一切复杂得令人难以置信。绝大多数哲学家肯定是在养鸡场长大的。人对一只鸡寄予如此大的希望，希望又如此悲惨地破灭掉。那些刚开始生命旅程的鸡雏，看上去如此伶俐机警，可实际上它们愚蠢得无可救药。它们真的很象人，可以将一个人对生命的看法搞得一塌糊涂。如果没有死于疾病，它们会等到你对它们的期望达到最高时钻到车轮底下—被轧死然后回归造物主。害虫们感染小鸡，大把大把的钱不得不花在药粉上。成年后我看到有一整类书籍是关于教导人们如何通过养鸡来发财致富的，这种书是给那些刚吃了善恶果下肚的神人看的。这是种盲目乐观的书籍，它们声称有抱负的普通人只要有几只母鸡就能大有收获，千万别上当。这种书不是写给你看的。到阿拉斯加的冰山上去淘金，把宝押在政客的诚实上，如果你乐意大可以去相信这世界每天都变得更加美好，正义总能战胜邪恶，但是千万不要去读那些养鸡的书，那不是写给你看的。

大意无非讽刺地说，和大家想象的不同，鸡实际上是种非常愚蠢和难伺候的生物，靠养鸡发财是做梦。相信养鸡可以发财的人和鸡一样愚蠢。结合原文的上下文，深层的含义应该是在讥讽那些做着“美国梦”的人的愚蠢。
