I don't think that there is anything that any college can do to correct the deficiencies in individuals. These students aren't 14 years old when they attend university. Students who want to learn do learn. Students who don't want to learn don't learn. It really is that simple.
Colleges cannot just shovel experience and growth into a young man or woman. The young man or woman must be seeking education and growth and then they can use college as one vehicle for that process.
Once again, you are right. The ones who want to learn belong in college. Those who do not should be in the workforce. Howver, College is now part of the progression of life and everyone attends. Graduate school is becoming the same. We know the lack of basic skill comes from two sources. The federal governments involvement in lower education and the lack of supplementation of those skills at home. Let the teachers teach.
