To an economists who imagines that we have a free job market in Britain.
You don’t have a free market when 80% of the top jobs in every important and/or highly-paid job sector in this country including business goes to 7% of private school-trained personnel. Social groups made at Oxbridge also become job protection and promotion groups from then onwards. There’s a 20% slot available for individuals with good intelligence and/or socialization genes.
When all children are given as equal opportunities as possible up until puberty when destiny is largely fixed we’ll begin to approximate to a free society.
