Humm,
That's seems to be a part of it.
Countering the negative emotional impact caused by an increasing rise in levels of real world social and wealth disparity that started around the 80s and is still ongoing, shouldn't have been done by teaching children increased self-esteem without real achievement, as that tends to increase fragile confidence and poor handling of criticism, making many younger adults today even less capable of facing today's increasing real world challenges than they would have been if they hadn't been exposed to the self-esteem movement (?

"John Vasconcellos believed low self-esteem was the root cause of crime, teen pregnancy, and academic failure. In 1986, the California government created the Task Force to Promote Self-Esteem and Personal and Social Responsibility. New Age psychologists and self-help authors from institutions like the Esalen Institute laid the theoretical groundwork, claiming that children must love themselves unconditionally before they can succeed. The trend rapidly spread across the United States."
But I don't think low self esteem caused crime, teen pregnancy, and academic failure. Those issues were more likely (?) a by product of a less than healthy sense of belonging and emotional grounding, which both have low self-esteem as a symptom. In a way children do need to start out 'loving themselves', but the way to install that is not by "self-esteem without real achievement".
"Albert Ellis, an influential American psychologist, argued that the concept of self-esteem is actually harmful and unhelpful. Although acknowledging the human propensity and tendency to ego rating as innate, he has critiqued the philosophy of self-esteem as unrealistic, illogical and self- and socially destructive – often doing more harm than good. Questioning the foundations and usefulness of generalized ego strength, he has claimed that self-esteem is based on arbitrary definitional premises, and overgeneralized, perfectionistic and grandiose thinking." https://en.wikipedia.org/wiki/...
