content: The job can be easy or it can be a pain in the ass depending on the school and subject being taught. Even without teachers other professions would exist. They are a major tool in teaching but not the only one (some parents home school for example). I believe that teacher get on average paid fairly (like in any industry there are markets where you get paid more or less). My grandparents were teachers and they were able to afford a big house with big yard in the middle of a 3 million+ size city in a good area. Now that they are retired, they can still afford luxuries like a new Mercedes C class car and going on vacation multiple times a year. I do not believe that their job is the most important for the future of everyone. That in my opinion would be a farmer since without food you wouldn't survive. Doctors, authors, scientists, engineers, police, military, teachers, farmers, builders, etc are all important and depends on each other.
