Ncert cutting down book costs seems like a joke

Hardly any private school uses NCERT books to teach. They make us parents buy expensive books from private publishers. In the name of NCERT, they would ask kids to buy a book or two but NEVER use it. This news seems like a joke. Why doesn't the government do anything to curb these schools' arbitrariness? They do whatever they please be it expensive books, exorbitant admission fees or constant fee hikes! Even the bus charges fee for full 12 months, even though kids have holidays in summers and winters. And my child goes to an average school, not even a fancy one!
