I often felt this way with public education, even down to the elementary-school level. When I was in school, specifically high school, I felt appalled that my voice didn't matter. It was always some school board member telling me that they knew best for me. And certainly that is true to some extent; there are some insights adults will have that students just haven't been exposed to yet due to limited life experience. But they didn't even bother to ask us how they could improve school.
An elementary school kid can still provide great value. Ask them what they would change, and they may reply, "less homework". You know less/no homework isn't the best solution, but maybe what they're really asking for isn't what you hear on the surface. A plea for less homework could be a plea to make education more exciting, without necessarily changing the dial on homework. Is there a way to keep the same amount of homework, but make it more engaging or meaningful that it feels like less work? I think at times we need to dig deeper on people's feedback, past the surface.
