You are correct, in that if you are talking about remedial programs, they would benefit those who have already failed (by the virtue of being remedial programs) to achieve something that is considered normal to achieve. However, if you're talking at general education programs, not specifically targeted and limited as remedial ones, I think my point still stands. I'm not saying remedial education is not important, but I think it's a different field - like a gym and a hospital, both aim for people to be healthy, but they address different populations by different means.
