Despite our (likely inferior to other countries) educational system, high school and college graduation directly benefits children. By graduating high school, a student will have a minimum level of knowledge (basic literacy, arithmetic) applicable in society. A higher national high school graduation % is better than a lower %.
Advocating students to drop out of high school for community college or trade school is not scalable. Today, ambitious students take AP/Honors/Community College or learn trade crafts after school hours. Blanket favoring kids dropping out of high school is irresponsible as it hurts their future.
