Sir: Children are the beauty of this world but many of them cannot go to school due to financial problems. Thus, they are pressured to earn a living for themselves and their families. It is a fact that there are many children who play a key role in sustaining the economic life of their families. The government should make elementary education compulsory, and distribute free books among students so that their parents might be able to get some relief. SANA SARFARAZ Karachi
