"why don't you just give up?"
Yes, she should give up...give up public schools.
When the government takes children away for 7 hours a day and then tells the parents the children need 1-2 hours more each night, when is it family time? If 1-2 hours a night, why not 10?
Give me a child for just 3 hours a day and they will graduate any engineering school in the country by age 18. In public schools children can barely read by then.
In SOME public schools this may be true - but not all.
Painting all public schools with such a broad brush is the same thing as saying any parent who doesn't homeschool shouldn't be a parent.
There are good public schools and there are also parents not equipped to homeschool. I should know because my daughter is in the former because I am the latter.
And, don't forget that the "government" (aka shrinks) now wants to test all kids for psych problems so they can put them on drugs.... another reason to keep them out of the public system.
