Why we go to university?

Nowadays, almost everyone go to university. It has been long time, at least in Thailand, that people who are able to work in a good position in a good company have to finish their degrees. In my view, going to university has a lot of advantages, namely upgrading knowledge, finding some connections and getting new experience. However, there are some drawbacks such as lacking of practical skills and improper method of learning for some people.
University and college are the most perfect places for getting professional knowledge. Cutting-edge technology and new knowhow are found most in university because there are many sophisticated professors who try to research for deep and specific subjects. In addition, brand new tools and supportive equipment encourage students to learn quickly and efficiently. Moreover, being with students who have the same interests will push them to achieve their goal (I guess you meant "goal", isn't it?). 
Another good reason why people have to go to university is connections. Students can get some connections while there are studying. It is likely that people who attain the same class support each other when they grow up. Besides, fresh graduates might get some benefits form their alumnus by getting a good job or technical support.
Students can also earn precious experiences when they are in university. There are many activities that amend students to be more mature and be ready for working life. Doing some activities such as living in a dormitory, joying a cheering club can literally improve their social skills. Being a volunteer implant a seed of good citizen for their society. This is an advantage that is beyond aspect of higher education.
However, going to college does not guarantee a successful life. Some say going to university lead to lack of practical skill, fresh graduates of some engineering courses, for instance, find it is difficult to deal with real problems on there working site because they just have learnt technical knowledge but not practical. What is more, some very successful people such Steve Jobs also did not finish his degree. Nevertheless, such a case is rarely to happen and most of the graduates always find jobs easier than those who do not have a certificate paper.
In conclusion, I think that benefits of higher education outweighs going straight to work or serve military after finishing high school since students can get significant improvements in terms of knowledge, job opportunities and invaluable experiences.

Excellent essay! I totally agree with your point. You have just gathered all the most important aspect about it in a simple explanation.. congrats!
