The reality is, there are some in our society that don't have the ability to do college level work. There's nothing wrong with that, but it is, what it is.
I have a relative who is mildly ********. I'm sure there's some special program in place that would have "allowed" him to go to college, but to what purpose? It's not like he would have come out as a Dr. or Lawyer or even on management level that would justify the expense of taking out student loans. Instead he was set up with a job coach, that assisted him in getting a job in a restaurant, where he has worked for the last 30 years. He's a valued employee at that restaurant, he receives an occasional COL raise, and is able to support himself just fine.
I also have a son who was smack down the middle average in High School. He's always been an outdoor type who would consider a desk job to be equal to a prison sentence. For him, a college education would have been a waste of money. Instead he preferred to work in a field that allowed lots of muscle and sunshine. For him, it made more sense to sign onto an apprenticeship, learn a skill, and work his way up the ladder that way.
Not everyone is meant for college.
