The point of education (or public policy in general) is usually not to assign moral blame. You can personally assign blame to anyone you want, but society has a harder problem : maximizing good outcomes. That means policy has to account for people that are lazy, people who have bad intentions, people who are stupid, and so forth. Society can't pretend those people don't exist even if you can, because if they end up uneducated, jobless and ignored they will just cause huge problems later. While you might feel good about blaming them for those problems, wouldn't it be better to prevent them in the first place? It is better to provide the best possible educational track that we can and try to make sure they have a viable career or work path open to them.
