We live in a world where two years of college are almost required to make even a lick of sense of it. Four years in a discipline like engineering, dental hygiene, or accounting is enough for a good job. And, a minimum of six years in anything else is needed to even get a sniff at a good salary right out of college. A 4-year degree in Chemical Engineering, for example, is probably worth more than most Mater's Degrees and even a few PHD's in the liberal arts.
Of course, there is always the option of career development right out of high school through specialized vocational training, like HVAC, for example, but that leaves a person vulnerable to changing technologies, as we see with countless professions that no longer exist. Still, I would not be against a son or daughter becoming an underwater welder, electrician, hair stylist, robotics technician, web developer, etc. But, make no mistake, they are still left at a disadvantage when adapting to changes and understanding the world around them.
