Colleges nowadays are very hard to get into. A lot of them have overly high standards that not very many people can achieve. College is hard enough and now there is extra stress on getting into a better school. This effects future career opportunities. Receiving an education from a less known school makes it harder to get a better job.
Going to college and getting a degree is practically a necessity in today's society to have any sort of success in life. However, there is also the same amount of competition for colleges as there is for jobs and someone graduating from a college with esteem will likely be hired over someone from a little less well known college. But these well known colleges are very competitive and it is very difficult to get into them. A lot of them allow only a very small number of people in per year and those few people have to have essentially perfect grades, extra curricular activities and special skills.
As the Rolling Stones once said, you can't always get what you want. It is a hard lesson for some people to learn that life is not always fair. What value does a prestigious college degree have for a school if anyone who wants to can get into it? Sometimes you have to bust your butt to reap the rewards, and college is no different.
If it was easy for everyone to get into the top colleges, then Harvard would be a party school. It is difficult to get into the top colleges, but not too difficult. If you are worthy of the college, then it should be easy for you to get into the school. They don't let just everyone off the street be able to attend, you have to have certain qualifications. If you complain about how hard it is to get into the top schools, you probably wouldn't have been able to get into them anyway.
