I think that a college education can be very valuable. To the right person with the right focus. Joe or Jane Smiley with no real work ethic and a lazy mind isn't going much farther than assistant manager at McDs with a Liberal Arts degree. But, then they wouldn't go far in the trades either.
But, a person who learns to THINK is going somewhere. Big difference between being able to make it through school and learn a bunch of stuff, pass test and graduate and learning now to really use your brain.
Ask a bunch of recent HS grads this simple question. I have a hole that is 3' wide, 2 yards long and 18" wide. How many cubic yds of concrete will it take to fill it up? Mostly deer in the headlights looks. They were all supposedly taught the facts and basic math needed to solve this, but 90% of them can't put it together and solve this simple problem. Can't think. The college Liberal arts majors won't do any better. But, they can probably tell you Chaucer wrote Canterbury tales, which nobody really needs to know.
Now go ask someone with a real degree like Engineering. Way more apt to get the correct answer. Although I have met a couple engineers who proved that with time and money you can get an engineering degree and still be dumb.
I know one bright young engineer and am sure he is being groomed to become a plant manager for a refinery company. He is educated and smart. He will end up making major money and become a multi millionaire if he wants it.
I also know a kid (under 30) who took a bunch of welding classes in HS. Got a job welding at 17, learned to weld pipe, both stick and tig. Started making in the mid to upper $30s per hour, but after the mandatory 7 years of work in the field he went and paid a few grand for the 2 week class, studied and passed the test to be a Certified Welding Inspector (CWI). Worked for me on his first job as a CWI and was green, but willing and would listen and make the effort. That was 2 years ago. I worked with him on the last job I was on. He was getting $55 an hour, 12 hrs a day, 13 days on, one day off. Thats over 5K a week, not counting the $115 a day per diem. He was only on that job 8 weeks, but made over 40k in wages. He will go out on another job after hunting season is over. Can pick and chose his jobs, work 6 months a year, enjoy life and family the other 6 months and still knock down well over 100K. He got a nice bull moose and a wolf this year. I myself have only worked 2 easy jobs this year for a total of 14 weeks and made over 55K. I don't look for work at all. I am 66, semi retired. I do answer the phone and say yes or no. Mostly NO unless it is sweet. I am not going to work again till next March and that will be about 12 weeks with a couple weeks of 40 hours in the beginning setting up, then roll into 13hr days till the end then maybe one last week of 40 or so shutting it down. I don't really need the job, but, I want a side by side ATV and momma wants an addition and a pond. That will probably be my last hurahh. Unless, its a real short easy one and I want something.
PS. I have 2 brothers that do what I do, we all make way more than the family scholar, who has a masters in fine arts. He works all year long. We pick and chose. I guess we do have an educations, we were just paid well to get them. I do have 3 profession certificates.
