I think not. I believe that this is due to the level of difficulty of the courses required of teachers. Before teachers around the country slam me for saying that, I apologize, but I have been there. I have also seen the ones who were born to teach, and they are few and far between. Even if they are wonderful teachers and love what they do, sooner or later, they will be bogged down, burned out, and they will lose their spark and their ability to inspire their students.
Some people think homeschooling is easy.
This may seem that I am contradicting myself, but I'm not. Homeschooling is not for cowards. There will be days filled with doubt, arguing, and times you want to lock your kids in the closet. Days will come when the kids will whine, drag their feet, and take forever to complete one measly assignment. You will know your children as those who send theirs off for the majority of their waking hours do not.
