This is what it is, and it's sad that it's so normalized that people are defending it.
Everyone knows the kids aren't technically required, but they're "required" by social pressure.
I remember having to go door to door selling things when I was a kid. It may have been voluntary in a technical sense, but I was pretty well mandated to do so if I wanted to be part of that group with my friends. And there was even more pressure from my mom and dad because they didn't want to be the family whose kid didn't do the thing.
I think it's time we start taking a long hard look at some of these things like fundraisers and de facto coerced employment of youth (without pay) and ask ourselves if a healthy system would allow this.
