Families depend on their children financially. Some are calling for the government to offer a small sum of money to each student who attends school.
But so far the government maintains it cannot afford it. Even if such a scheme was introduced, it would be hard to decide which families should receive the money.
The last time the government examined the issue, it concluded about four million children have full and part time jobs. The Bangladeshi Labour Institute believes the number is closer to eight million and rising as the population grows.
