Most homeschoolers are doing one or both of two things - starting their own businesses and/or shaving 2 or more years off of college by KLEPing out of courses or taking dual credit courses so that at 18 they start college more or less as Juniors.
What I had in mind RE: homeschooling is the emphasis on mentoring and apprenticeships over and against lectures and classroom learning. Some amount of book-work is necessary for technical careers, but even in the high-tech arena there is no substitute for being able to work side-by-side with an experienced mentor. If we could ditch the college model for a mentor-based training model we could show the rest of the world once again what made America great in the first place. (Hint: It wasn’t MBA’s.)
