This discusses what "elites" think a lot, but does not discuss why that matters
From 1950 to 1979, times we think of more stable families, the Gini index in the US never went above 39. From 1993 to 2019 it never went below 40. There has been a shift where working class men were more on par with the heirs of the USA, but things have shifted so this is less so. The shift in power to what elites think is more important coincides with a shift of income and wealth to these heirs.
Another problem cited is a lack of "a submissive attitude toward the boss". From the 1930s to the 1970s, US workers had larger union representation, and engaged in sit-down strikes and wildcat strikes. This does not sound like a submissive attitude toward the boss. As the heirs have successfully cracked down on worker organization, this becomes individualized, with submissive workers getting low pay (according to this) getting work, and those not "submissive" as this says, who seek higher pay not being connected to production, leading to instability outside of the workplace.
There has been a conscious shift by the mentioned elite to remove workers representation, power, organization, pay and stability. These are seen as less of a problem than some supposed lack of a paternal attitude from the elite to lecture the working class about their lack of a "submissive" attitude as this says.
It's the same nonsense we've heard since 1980, from funded think tanks and various establishment institutions, it goes hand in hand with the policies and shift in income and wealth disparity which led to this.
