What would the corollary be for children who are all forced to wear the same school uniform? Higher self-esteem? greater empathy?
I think it would depend on when you began the uniforms. If kids have never done anything but uniforms, I think your scenario could easily play out. However, if kids had worn what they wanted until 6th grade, and then the rule was implemented, I think there would be resentment of the rule and kids would try to rebel. Plus, people would still know who belongs to what “class” in school.
