Absolutely. There are already some of these. For example, it takes about two years of vo-tech training to get an AMT degree and be certified as an aircraft maintenance technician. Most airlines have payscales that top out at five years of seniority with an annual salary of about $60,000 or so plus benefits. Not too shabby for someone less than 25 years old without a four-year college degree.
There are other examples like this.
The trouble right now is that everyone wants their kid to go to college. If you took them to task and asked them why, half of the people wouldn't be able to give you a good answer, other than "that's what you do after high school". For the other half, the answer would likely be some variation on "so that he/she can get a good job". Back to your original point - if you could obtain a good job without a college degree, there would be no need for college.
Voila. The liberal, America-hating college campuses of today would be in trouble. College tuition would go down, and some of these ex-hippie commie professors would be prevented from polluting the minds of our youth and actually have to get a real job.
As I also mentioned...all of our political leaders have college degrees, many have legal backgrounds, and most studied political science....is all this necessary to be a leader?
