"Social Mobility Index" always seems like a particularly weird metric to me. Not just in the usual issues of vanity metrics or gaming the system or whatnot, but also because, I'm not sure that maximizing it is even a desirable outcome. It's a weird measure of like, societal churn. I'd much rather look at quality of life metrics across all citizens than just check if the outcomes of children are uncorrelated to their parents decisions.
