I’m going to ignore your insults and escalatory language and just point out the fact that the WEF’s definition of social mobility is vastly different than the one I mentioned. You’re conflating two completely different metrics. I’m happy to learn new things, have a constructive discussion, and to admit I’m wrong if that’s the case, but not interested in engaging in mud-slinging based on things my college teacher said twenty years ago.

A sibling comment to yours explains succinctly why your comment misunderstands mine: standard of living in the US is higher than India. The WEF’s metric is based on ranking the standard of living of each country against each other. It can be simultaneously true that the US standard of living is higher than India, and also that people born lower class in the US improve their lot at the same rate as people in India.
