In European history when child labour was common, as well as in contemporary child labour of modern world, certain cultural beliefs have rationalised child labour and thereby encouraged it. Some view that work is good for the character-building and skill development of children. In many cultures, particular where the informal economy and small household businesses thrive, the cultural tradition is that children follow in their parents' footsteps; child labour then is a means to learn and practice that trade from a very early age. Similarly, in many cultures the education of girls is less valued or girls are simply not expected to need formal schooling, and these girls pushed into child labour such as providing domestic services.
