Yes, and the Raspberry Pi is not designed for them. There is no reason it should cater to everyone, it's designed for those who aren't experienced with programming, hacking and reverse engineering so they can start on their learning experience without a large financial barrier to entry.
You're missing my point, which is that high school students are capable of this kind of thing, and it would be perfectly possible to push yet more of them along that route given the right environment and attitude.
