The article doesn't touch upon education much at all, which I believe is a central part of social (im)mobility. Problems arising in society later on will simply stem from the early life of members of society, not afterwards. It's a common principle that education is the key to societal equality, in some way.<p>All I can offer is my story on this. I've lived in the UK all my life in all sorts of regions from those of lower working class (my hometown) to my recent years where I've lived in rather upper-class "lawyer-doctor-business owner" regions. The difference in education between the lower and upper classes is stark. Let me explain.<p>Upper-class children are enrolled in schools of like-minded high-achievers full of entrance exams and interviews (provides a non-zero floor to student "intelligence/quality" at the school), and strict rules/discipline. They are further pushed towards degrees leading to higher paying careers - Finance, Medicine, Law, by their families and the schools themselves. Their families purchase extra tutoring, they have smarter parents (this is a positive feedback loop across generations!) to guide them, and so on...<p>Compare this to lower-class children, who, in the UK (and i'm pretty sure everywhere else essentially) are enrolled in "state schools" (free). These schools have no entrance requirements (there is zero floor for student quality), the families almost never purchase extra tutoring, and are much less pushed towards "meaningful" degrees. The schools offer equal environments to the best and the worst of students.<p>This imbalance in education (and by extension upbringing in general) is what seeds everything else. And indeed, in the past few years the UK government has recognized all the above. How they plan of solving it? The reintroduction of "Grammer Schools"! These are state schools (still), but _do_ have enterance requirements, thereby allowing lower-class students of high intelligence/quality a chance to separate from the worst students in state schools and enroll in a more challenging education. There is much debate in the UK whether this will work, or will simply just allow children of rich families to more-often/further separate themselves from poor families. Time will tell.<p>That's my 0.02c anyway: Education.
