Though the article could have done a better job explaining this. It's like a reverse phenomenon of "do as I say, not as I do". That's probably what the article meant but I'm skeptical that it makes a significant difference in behavior. There are other positive behaviors that "social apex" people say and do but lower income people as a group still don't imitate them. Strictures like "don't use tobacco," "don't impregnate/get impregnated as a teen", "drink unsweetened iced tea instead of Coke," and "use free time to exercise instead of snacking and binge watching" are significantly less popular among low income/status groups than high income/status groups.
