If we had no homework one of the following would happen:
1. The west would fall way behind in technology in the next generation, as the next generation would have a much lower level of technology.
2. See above.
Children would receive less education. Thus, they would not be able to cover as much curriculum in a single year due to not doing as much work, and the next generation would be a much lower intellectual level in the next generation. At grade twelve, children without homework would probably be around the same stage as a grade ten student is today. Intelligence = Progression. Ignorance = No progression.
