We as a society make judgements which assign more value to some occupations than we do others and it is not unusual for those values to be at odds with the values of other societies. In the UK engineering and manufacturing do not enjoy high status and hence we have nearly lost our industrial base the Germans on the other hand value their engineers highly and respect and reward them accordingly. They have a thriving industrial base. We look to the Banking sector to generate wealth and all they have done is bring the country to its knees.
Chaplow's Shiny Head raises a very important point. Some knowledge is more highly valued than others. To be a builder you need knowledge of structures, construction processes, materials, planning law, health and safety legislation, standards and specifications, project management, people management, financial and accounting skills, knowledge of continually changing building regulations and the ability to bring a wide range of skills to bear on the safe completion of a building project. This all involves a very high standard of occupational competence involving knowledge skills and understanding acquired through education, training and experience and most importantly all of these bear in a very positive way on all of our lives through the environment in which we live.
As a society we dismiss the non academic preferring to value the academic more highly. That is why politicians talk about the A level exam as the gold standard and reject the value to young people of vocational qualifications even though they are in many cases as rigorous and demanding and often of more value to the young person.
Employers are quite right to complain about how poorly prepared young people are for the workplace. Schools are run by people who studied academic qualifications and went to University and they prepare young people to follow the same route and expect them to go to university.
The kids who are not going to succeed along that route are left with nothing.
