This encompasses the infrastructure and reform of the system of education. In order to solve educational problems, we must approach at system-level.
Classroom size is dependent on staff availability and the student-to-teacher ratio within a school system. For example, Los Angeles, California's Los Angeles Unified School District (LAUSD), the second largest school district in the nation, has an abundance of students which makes it harder to shrink the classroom size without hiring more teachers (made more difficult by the teacher shortage).
With too many students in one classroom, we are more likely to strip students of their right to share their voice, to be part of the conversation and be on the receiving end of a responsive curriculum or responsive teacher. Without smaller classroom sizes, we are risking exclusion in a place where we must produce more inclusion.
