Isn it the governments responsibility to educate children?
No. It is the parent’s responsibility. If the government was responsible, it would be inundated with law suits from failed children and their irate parents. As it stands, when a school fails a child, the parent is to blame. This is how come the government is able to get away with an education system which leaves one sixth of all school leavers functionally illiterate (according to its own statistics). Ironically, you don’t see the government punishing parents who fail their children by keeping them in dreadful state schools!
