Should higher education be available to all?

Before discussing this topic, we should consider how higher education was originally designed. Why is not university education compulsory? What kind of study does university provide? I believe that Studying at university ought to be available for only those who want to academically specialize themselves in a specific field, unlike most of today`s university students. However, why do some people believe that a college or university education should be available to all students?  

Since the number of universities has increased, universities have been plunged into changing their function: teaching academic theory to training practical skills. That has been the way for them to attract prospects and survive. The fact is that it is really hard for each university to keep getting enough students. Today`s higher education just emphasizes that it enables students to stand on a better starting point for job hunting.  

Whereas, as there are some special facilities for job training at the higher education`s level, the function of university should not be changed anymore and I think we should reconsider how higher education should be. I really doubt how many students are purely seeking to satisfy their academic curiosity at university.  

It is pitiable that university graduates are no longer specialized intellects. Making higher education available to all students is no more than making the phenomenon worse.
