Education is essential if we want to give children a chance at social mobility. Traditional schools have their problems, including those you list, but at least children taught in them can get some qualifications, and those qualifications give the children a shot at doing something other than the same as their parents. If the only education the parents themselves got was walking a pony up and down a railway line, it's unlikely that they are in a position to effectively homeschool a child.
