"More grassroots" can be opposed by terms such as "establishment", "elite", and "hierarchical". These antonyms describe a more structured, controlled, and exclusive approach to social or political movements, which contrasts with the bottom-up, community-driven, participatory spirit of the grassroots. While some may argue that the establishment provides stability and expertise, others may feel that it amplifies the voices and interests of the powerful few, and neglects the needs and aspirations of the many. Whether we prefer the grassroots or the establishment may depend on our values, experiences, and goals, but it is important to acknowledge and respect both perspectives in a diverse and inclusive society.
