Due to the limitation of economic level and education level, most people at the bottom of society only touch a corner of society, but they are not aware of this problem and have no pursuit to solve this similar problem. It is enough for them to have enough food, clothes and money to spend. And some people they come into contact with, from the bottom to the top, may have made a lot of money through hard work. Maybe they haven't received a very good education, but they still live a better life than scholars. This is an excellent proof that they put forward the theory that reading is useless.
