There are always people who lack that very natural skill needed to solve problems...that heuristic intuition with logic and thinking skills that cannot be taught easily.
Actually, logic and thinking skills can be taught - and that is what a four year degree does teach- people flunk out of college who can not grasp those fundamentals. And it is the reason why law rewuires a four year degree and after that, law school and why bedcoming a doctor requires a four year degree and after that , med school. It if were just about skills, then medicine and law would skip college degree and just send applicants to law school or med school. But they don't - because memorizing legal or medical is not the same as abstract and moral thinking skills - logic, reasoning and the ability to synthies opposites or opposing viewds vs simplistic black and white or follw A and B happens is what the humainites teaches. Developing that kind of thinking, which philoophy, religion, the humanites imparts is eduation for the sake of educaiton - it is not about jobs , earningr, or incomes. People can self educate and get exposure to studies outside of a four year degree of course, but the degree is open to anyone who can get into a school and maintain the grades nd stick it out to finsih and is a way for employers to have a verfianble proof of it. Pililng on more skill set courses is not the same thing. And we see that in posters here who managed to memorize enough to get licensed but then lack the ability to apply it.
