If the system tries to force compliance, it is invariably attacked for disproportionately penalizing minorities (even if the penalties are proportionate to non-compliance rates). How is the system actually going to force compliance without being attacked as racist?
It seems very logical (however shameful) that the system would optimize for passively allowing students to age out of the system, as letting minority students fail doesn't have anywhere near as much blowback as fining or locking up disadvantaged people for truancy.
