Final answer:
The question confuses the subject by mentioning Jim White, when it should be focusing on Jeremy Iversen's experiences outlined in 'High School Confidential.' The key issue is the long-lasting impact of negative teacher labels on students.
Step-by-step explanation:
The question appears to stem from a misunderstanding. The subject at hand is not Jim White, but the experience of Jeremy Iversen, who wrote High School Confidential.
In his account, Iversen relays the negative impact that teacher labeling can have on students – noting that such labels can be hard to shed and may influence students to "live down to" low expectations set by those in authority.
This is particularly harmful when the individual being labeled is a vulnerable high school student, rather than someone like Iversen, who was an undercover graduate from a prestigious university.
Therefore, the information about Jim White being fired from a school is not directly relevant to the context provided, which focuses instead on the dangers of negative labels in educational settings and their potential to affect student self-esteem and performance negatively.
