That’s a great question and a very real topic in my house right now. In my opinion, no, college does not make you a better person. Only you can make you a better person.
I am a mechanic. I started turning wrenches professionally in 1988. The same year I graduated high school. My wife is also working with just a high school diploma and she does payroll for a small business. Am I rich? No. But I own my house outright and literally have 0 debt. So the trades have been good to me.
I have two sons. I have always encouraged them to go to college. Not to make them a better person, but to have more doors open to them as they find their path in life. I am paying for their college, so there is no reason they shouldn’t. My oldest is currently at UMD with a chemical engineer major. My youngest is getting ready to start high school, and if I had to guess, he will go into the trades. He is every bit as smart as his older brother, he is just a lot more hands on. A lot like me! Even though I will still keep encouraging the college path, I will be proud of him and support him regardless of which path he chooses.
Good decision and hard work will make you successful in life, regardless of your education.
College does not make someone a better person. Many college degrees are absolutely useless. But there are many degrees that can open doors and give opportunities which won't exist otherwise.
I have the utmost respect for Doug. I have a BS in Industrial Engineering, BA in Statistics, MS in Industrial Engineering, MA in Teaching, and am currently working on an MBA. I'm book smart, which makes me a good teacher. But my abilities pale in comparison to Doug. He has skills and abilities that I only wish I had. In many ways, I am envious.
As an educator, I have seen how this push for college has hurt so many young people who would have been better off if they were steered towards a vocation or a skill. So many of my past students failed out of college and were left with a ton of debt. Many others chose useless majors and can't find legitimate work to pay off their astronomical student loans.
I have three girls, all of whom are expected to go to college ... with the intention of a STEM major. They can minor or double major in something else "fun" if they want. But their primary degrees must be something which can earn them a well paying career.
But college does not make a person better.
