Without a good knowledge of the English language a graduate is severely handicapped in the job market. This does not mean, however, that it is necessary to major in English. A student can take courses in composition and literature which will improve his or her English, and good English can be learned in studying history, philosophy, and many other subjects. A student can, and should, also continue to improve his or her knowledge of English independently by reading good books and magazines and by practicing writing essays, stories, articles, even poetry. It is very difficult to become proficient in English (or any other language). It takes years of study and practice. It includes adding to one's vocabulary, conversation, listening, following intelligent and informed persons on TV and radio. It is actually a lifelong pursuit, but one with increasing satisfactions.
English majors who go out into the world looking for jobs are often in for a shock. They are scattered to the four winds like dandelion seeds. Many end up in the business world as management trainees, pharmaceutical representatives, bank tellers, real estate salesmen--they are to be found everywhere because there are so many English majors and there is usually a demand for clean-cut young trainees who can express themselves well in English. But there is a danger of ending up in a line of work that is not compatible with one's interests and personality.
Every intelligent person who lives in an English-speaking country should strive to become proficient in the English language but not necessarily expect to make a career out of just being able to speak and write good English.
