In ancient Europe, only the rich and Nobles had the right to invite teachers to teach their children while the poor kids could not learn anything. But nowadays, teacher has become a common occupation. In other words, there are so many teachers. So I think the social status of the teacher decreases a lot.

A prominent reason relates to the development of technology. Many innovative technological products can replace the role of teacher. For example, some artificial intelligent robots and smartphones can teach children, such as vocabulary and grammar. Second, with the help of the Internet, some teachers can record their lectures and upload them to the website. So students could pay for these study materials and learn by themselves, thereby minimizing the role of a teacher.

In ancient times, however, few people could master enough requisite knowledge for the teaching position. The lack of teachers increased the value of the teacher. In ancient China, students had to carry meat, which was treated as expensive tuition, to teachers to show respect. Teachers could even refuse to teach some students due to the difference in social status. That was just because few teachers could give lectures, and almost all the students appreciated these venerable teachers. In contrast, today, there are many professors in universities and teachers in schools. Most of them are competent, so their value decreases because of so many competitors.

In a capitalist society, the financial value of teacher can be determined. Today we often evaluate the cost of a person by their income. Specifically, teachers do not get paid as much as programmers or doctors, which means teacher doesn’t have a high social status compared with these high-income people. However, teachers were highly paid in the past, especially for the teachers teaching nobles.

Above all, high-technology products, popularity, and current income of teachers have led to the decline of the status of teacher. It is the fact that teachers nowadays are less appreciated.
