"Mobility at every level has never been greater" is a completely unfamiliar claim to me. I literally can't find a single plausible source saying that about socioeconomic mobility - they all say it's been flat or falling for at least 20 years. Are we maybe talking about different forms of mobility? From Wikipedia: "In recent years, several studies have found that vertical intergenerational mobility is lower in the US than in some European countries.[1] US social mobility has either remained unchanged or decreased since the 1970s.[2]" "A study published in 2008 showed that economic mobility in the U.S. increased from 1950 to 1980, but has declined sharply since 1980.[3]" "A 2013 Brookings Institution study found income inequality was increasing and becoming more permanent, sharply reducing social mobility.[4]" [1] https://www.nytimes.com/2012/01/05/us/harder-for-americans-to-rise-from-lower-rungs.html?sq=mobility&st=cse&scp=1&pagewanted=all https://www.nytimes.com/2012/01/05/us/harder-for-americans-t...
