why children works ?

I think,Children works for the social injustic and economic problem.Besides this,the more specific reasons for children may be poverty and family size (In Bangladesh,family size aaverage 5 person.In families where children work,the father often work rickshaw puller or day labourer.Also the mother works another houses as a servent.For this reasons,they loosing interest in their children.This families moving here and there for looking different kind of new works.So,without stable income children are bound to work in small age.Poverty leads to quarrels,tension.),Migration (In general neglected children and different natural calamities are involved for migrated to the cities with their families or alone.The children works different way.)Child law and rights (child labour in bangladesh do not protect working children.Employers prefer children as they are cheap,productiveand obedient.They working indutrial sector.For reason they are demanding and incresing day by day for indutrial sectors.)Also,illiteracy and family breakdown etc.
