For those who want to create their own curriculum for their children, or who want to further their own education with self study, there are a growing number of both serious and casual ways to achieve this using the internet, much of it for free.
Thankfully, the mainstream academia is losing its monopoly, and many jobs nowadays pay a lot of attention to the self-taught, no matter how the knowledge was attained. You can even study for a degree and only pay once you're ready to graduate.
