What was common for the 19th century is illegal today. Anyway in many countries child labor is still widespread. It concerns mainly developing countries in Africa, Asia and Latin America where rate of child labor is extremely high. It happens mainly because it is cheap to exploit children who have to work sometimes 12-hours shifts. Quite often the work is very dangerous and harmful for their lives. The conditions are terrible. But it seems like nobody cares. They say that the practice of employment of children decreased in the 20th century. Anyway the statistics is shocking.
