In Australia, our education system is staffed by people who have never had real jobs, so only know what they have ben told or have read about. Who does the telling and who writes the books ? The kids are victims of their environment
As a teacher, this is an argument I have heard many, many times. Teaching is a real job -just like banking, working in an office etc. It may not produce an item where manufacturing would but it does produce well rounded, intelligent, knowledgeable young people ready to take on the next phase of their journey - whether that is a “real job” or an office role or teaching.
Recent initiatives have encouraged older people to go into teaching, those who have had a “real job” first - not many have stayed longer than a year or two as the job is not what they expected.
Just because you have been to school, college, university does not make you an expert just like buying your good in a supermarket does not make you an expert in the retail industry.
In relation to your countrymen, I have worked in schools which have had exchange programmes for teachers based in Melbourne schools. The teachers who have spent a year in the U.K. have been excellent, dedicated and professional and the teachers I worked with for a year when in Melbourne were certainly not failing the children in their care.
As for writing or reading the books, teachers today are the most qualified they have ever been -all teachers have to have a degree, the vast majority have a masters degree (compulsory in the US after a number of years) and there are more PHD Qualified educators than ever before.(this includes your countrymen)
I do not know what you did for a job but I have always held the opinion that I would be foolish to tell someone how to do their job, or to tell them they are doing the job wrong, when they have held that career for a number of years, I simply ask for the same courtesy.
