For one, meth addict or homeless or violent drunk parents would probably not be able to do homeschooling. Then, homeschooling is probably only better because it is 1 on 1, and not 1 on dozens as it is in public schools. For me, it doesn't make sense that parents are somehow magically better than professional educators, if you assume that the professional educators are actually motivated and care (there are people in this thread who are arguing that generally parents care and professionals don't).

Two distinct groups of people who for different reasons show kids do better with parents. The point is parents are better at raising kids an people who are trained but not family.

Its not all one to one though. Even when it is one to one it is almost always far fewer hours than at school. A lot of school kids get one to one attention of top of classes (tuition for teenagers has really taken off here in the UK in recent years).

My kids did classes and online courses and taught themselves for some subjects and still did a lot better in those subjects than school kids do. There are advantages to being outside a system individualisation, efficient use or time, learning study skills and self-discipline, etc.

Most do, some do not care (they should not be in the profession, but they exist) or are demotivated by the system them work in.

They are also often constrained by the school system. They are pressured to hit metrics which are often not in the best interest of children (especially in the long term). It tends to lead to a lot of studying the exam rather than the subject, for example.
