I skipped 5th grade and I can't for the life of me really pinpoint what possible negative impact it has had on my life. And, even if you suggest that there really wasn't any positive, either, just as a sheer function of entering the labor force one year earlier, the lifetime income impact is quite significant. I certainly don't want to dismiss that I had one less year of fun elementary school times with friends, but it's fairly clear to me that the way we've organized schooling isn't really rooted in anything that really promotes the success of an individual, but more what is socially most efficient/easiest.
