As for me I would say a house wife is a woman whom we have to respect in society even though she is not a career woman (like lawyer, secretary, doctor, scientist, you name it), being a house wife is a career on its own.
En cuanto a mí, diría que una esposa ama de casa es una mujer a quien debemos respetar en la sociedad, aún cuando no sea una mujer trabajadora (como abogada, secretaria, doctora, científica, lo que fuera), ser un ama de casa es una carrera por sí sola.
