Teachers were more appreciated and valued by society in the past than they are nowadays.

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, the[ article error ] teacher has become a common occupation. In other words, there are too[wrong adverb: too…to  ] many teachers in society. So I think the social status of the teacher decreases a lot.

[A prominent reason relates to  ]With the development of technology, many [ . Many innovative ]advanced technological products (have the ability to)[use one word  ] replace the function[/role  ] of the teacher. For example, some artificial intelligent robots and smartphones can (teach children basic knowledge)[wrong phrase  ], such as vocabulary and grammar. Second, with the help of the Internet, some teachers can record their lectures and upload them to the Internet[repetition -change word  ]. And[ Punctuation error with coordinating conjunction ] students could pay for them[ unclear pronoun ] and learn by themselves. As a result, students do not need teachers teaching in person, because they can learn by modern methods[, thereby minimizing the role of a teacher  ].

[In ancient times, however, few  ]Few people could master enough knowledge [requisite for the teaching position  ] in ancient time. The lack of teachers increased the value of the teacher. In ancient China, students had to carry meat, (that[ which ] was always[ absolute statement ] treated as expensive gifts and tuition)[wordy and unclear  ], to teachers to show respect. The[article error  ] teacher could even refuse to teach some students (due to the gap in status)[ unclear ]. That was just because few teachers could give lectures, and almost all the [ article error ]students appreciated them[ unclear pronoun ]. In contrast, today, there are many professors in universities and teachers in schools. Most of them are able to teach students[competent  ], so their values[word form value  ] decrease because of too[incorrect adverb  ] many competitors.

In a capitalist society, the [ financial ]value of the[article error  ] teacher can be calculated[/determined  ] by price. Today we often evaluate the cost of a person by their income. Specifically, (the salaries of teachers are not as much as programmers or doctors)[logically confusing  ], which (means the teacher doesn’t have a high value)[absolute statement  ]. However, teachers are[ grammatical error ] highly paid in the past, especially for the teachers teaching nobles.

Above all, high [wrong word  ]technology, popularity, and current income of teachers have led to the decline of the status of the[article error  ] teacher. It is the fact that teachers nowadays are less appreciated.

Teachers were more appreciated and valued by society in the past than they are nowadays.

In ancient Europe, only the rich and Nobles [ the nobles  ]had the right to invite teachers to teach their children while (the poor kids could not learn anything)[ absolute statement  ]. But nowadays, teacher has become a common occupation. In other words, there are so many [ more  ]teachers [ than there were in the past  ]. So I think the social status of the teacher decreases a lot[  considerably ].

A prominent[ / notable ] reason [ behind teachers’ social position  ]relates to the development of technology. Many innovative technological products can replace [ /are replacing  ]the role of teacher. For example, some artificial intelligent robots and smartphones can teach [ help  ]children, such as [ to acquire  ]vocabulary and [ learn grammatical rules  ]grammar. Second, with the help of [Assisted by   ]the Internet, some teachers can record their lectures and upload them [ recorded lectures  ]to the[ a  ] website. So students could pay for these study [ these  ]materials and learn by themselves, thereby minimizing the role of a teacher.

In ancient times, however, few people could master enough requisite knowledge [ requisite  ] for the teaching position. The lack of teachers increased the value of the teacher. In ancient China, [  many ]students had to carry meat, which was treated as expensive tuition, to [their   ]teachers to show respect. [ Even so, teachers  ]Teachers could even refuse to teach some students [ from a lower social class  ]due to the difference in social status. That was just [ in part due to a small number of qualified teachers.  ]because few teachers could give lectures, and almost all the students appreciated these venerable teachers. In contrast, today, [Today, however,   ]there are many [ competent  ]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 [  a ]teacher can be determined. (Today we often evaluate the cost of a person by their income.)[  unclear ] Specifically, teachers do not get paid as much as programmers or doctors, which means [ in general teachers’ social status remains inferior to  ]teacher doesn’t have a high social status compared with these [  many ]high-income people [ /professionals  ]. However, teachers were highly paid in the past, especially for the teachers teaching nobles.

Above all, high-technology products[ technological innovations  ], popularity[ unclear  ], and current income of teachers have led to the decline of [teachers’ social status   ] the status of teacher. It is the fact that teachers nowadays are less appreciated.[The reality is sad, but it is true.   ]
