7% worldwide seems to me a relatively high percentage in the context of college degrees, since that means more than 1 in 20 people worldwide have a college degree.
Another question to consider is whether getting into college should be extremely or very competitive, competitive (such as accepting 20-40% of applicants), somewhat competitive (such as accepting about 40-75% of applicants or having minimum admission requirements and accepting a significant number of but not all applicants who meet them), or whether college should be almost open enrollment (accepting almost anyone who applies); whether college should be seen as something that should be “elitist”, open to all that have graduated from high school (with a high school diploma or certificate or completion) and/or are physically and intellectually/mentally able to participate in college, or somewhere in between. If someone believes that college should be open to only the top high school students in terms of grades, I would expect that person to disagree that the majority of recent high school graduates should attend college.
However, personally I think that even if college were accessible to the majority of high school graduates, that does not necessarily mean that all of those high school graduates should attend college (I am not saying that I personally believe that college should be open only to the top high school graduates in terms of academic grades though). I also see purpose in the existence more practical and vocational post-secondary training apprenticeships, apprenticeships, or full-time job opportunities immediately after high school graduation.
Obviously some jobs require that you have attended and/or completed college for you to be considered for the job.
