It is up to you to decide whether or not it is worth it to you. There are people who benefit from it.
In my opinion, college education has declined in quality but risen in cost. More kids come out of college in debt and can't find a job. You are better off buying gold and silver and waiting four years instead of going to college. You would see a greater gain.
Also, I feel as though I learn much more on the internet than I ever did in school. Of course not all the information on the web is accurate, but either is it completely accurate in school.
If you want to change the education system you need to get government out of the way. The reason the cost has risen is because government guarantees loans for students. Since the loan is given to students it inflates the cost because the money for it is printed. The schools also know the money is going to be received so they raise the costs. All the government does is insure quality will go down and price will go up. This also makes sure that every kid goes to college who may not even be qualified for college.
Before government was giving easy credit loans to students, the students were able to work and pay for it because the cost wasn't so high. The same things have happened in energy, agriculture, and healthcare.
Most people have forgotten that the best way to learn a practice, is on the job. Unless your job is to become a doctor, lawyer, etc. We really need to get the government out of the way and allow the market to determine what the best education is through competition.
