Au contraire, homeschooling may require less instructional time that the typical parent wastes conforming his and his family's life to the demands of government schools. With the curriculum and support that is available, anyone can homeschool----as long as he wants to. For most, it is just a question of priorities.
"...homeschooling may require less instructional time that the typical parent wastes conforming his and his family's life to the demands of government schools."
I'll second that. I made the mistake a few years ago of having a foreign exchange student. He attended our local government school. I homeschool my two children, and putting up with the public school rigamarole for one student easily took as much time as teaching two did. Why people are so willing to put up with the public schools' running their lives, I'll never know. Freedom, thy name is homeschooling.
Two factors that can steal away the hours in homeschooling:
(a) slow learners that require more oversight
(b) fast learners planning to excel competitively
(c) number and age of learners in the environment
(d) the rigor of the curriculum
(e) the number and intensity of extra-curricular activites such as sports or music
(e) the occupational demands, aptitude, and discipline of the parents as well as all other circumstances and events which vie for time
