Final answer:
The theme is the corporate influence on education, emphasizing the need for diligence against cultural brainwashing and social homogenization facilitated by technology and teaching methods like 'teaching to the test.'
Step-by-step explanation:
The theme in the statement, "Now that School TM is run by the corporations, it's pretty brag, because it teaches us how the world can be used, like mainly how to use our feeds," revolves around the corporate influence on education and how it aligns with the broader themes of social homogenization, social fragmentation, and the impact of technology and media. This speaks to the way in which educational institutions might promote conformity and instill a corporate mindset in students, rather than fostering independent thinking and a true understanding of content. Teaching to the test and the use of technology, such as social media, represent techniques through which corporations can exert their influence.
Additionally, the theme points to a concern about brainwashing and the need for vigilance against cultural influences that lead to 'unnecessary human distress or damage to the living environment.' Moreover, the comparison can be drawn with the alienation of workers from their jobs, as students might become alienated from the true purpose and process of their education.
