What underlying societal mechanisms contribute to the persistence of traditional gender roles in family structures today?

Traditional gender roles in family structures persist today due to a combination of social norms, cultural beliefs, and historical practices. Many societies still hold onto the idea that men should be the primary breadwinners while women take care of the home and children. This is reinforced through media, education, and even family expectations, where children learn these roles from a young age. For example, a boy might be encouraged to play with trucks and pursue sports, while a girl is given dolls and encouraged to play house, shaping their views on what is expected of them as adults. These early lessons create a cycle that makes it difficult for families to break away from traditional roles, even as society evolves.
