Education isn't being skilled in a trade dumb ass
A slight disagreement. Being skilled is education, but that doesn't mean it should stop there or be limited to it.
Obviously some people can only handle so much so teaching them to use a mop, a leaf blower or even something as technical as a metal lathe may be their limit. I've flown with a few civilian pilots who learned the skill of flying, but lacked a lot of common sense outside the cockpit and, sometimes, inside the cockpit.
One reason many white-collar jobs, especially in management, and military officers are required to have a college degree is so they have a "well rounded education", meaning they know more than simply a skill or knowledge in a single subject.
FWIW, education doesn't have to include a piece of paper from a college or university. It can be autodidactic like Abraham Lincoln or in an occupation or profession such as several years in the military.
In Arbie's case, while I have no doubt he's very skilled as a machinist and in competition shooting, including reloading, it seems his education stopped there. While it's possible he simply quit or didn't care to learn anything more, it seems more likely he's simply unable.
Abraham Lincoln was born in 1809 to an illiterate father and a mother who only had basic reading skills. Lincoln himself did not receive extensive formal education. According to the sixteenth president of the United States, he only attended school every now and then. In 1858, he even described...

Meanwhile, Lincoln only borrowed books from a local attorney and studied legal cases intensively. He took on different kinds of casual jobs throughout his studies to sustain himself. Because he was at a disadvantage because he was self-taught, it took Lincoln four years instead of three before receiving his license. Lincoln had a sharp memory, but his mind was not as fast. It took his mind a while before he was able to grasp the concept at hand. Lincoln himself said that he was slow to understand, but he retained the material in his mind for a long time. He said further that his mind was like steel — hard to etch something on it, but near-impossible to erase the etchings on it.
As a Member of Congress
When he was serving in the House of Representatives, his friends thought it was hilarious that Lincoln spent his free time reading books inside the Library of Congress. However, his self-education enabled him to grow a scholarly power that showed its force in his speeches and writings. His power of speech was driven by his sound arguments and the well-founded knowledge he had learned through his non-stop reading.
