How does Montag think reading books will affect their lives

Millie whines that there is no reason to read books and that that their house will be burned down if anyone finds out. Montag responds with a passionate rant, asserting that they really have no concept of what is going on in the world and that those who seek to learn are quickly quieted, just like Clarisse and the old woman. He talks of the ongoing wars and how people all over the world are toiling and starving while they live well and devote themselves to leisure.
