More than 400 children from the National Movement of People's Children marched from La Quiaca, in the far north of Argentina, on the border with Bolivia, to Buenos Aires, the country's capital. The objective was simple, unappealable, and humiliating. They marched to demand the fulfillment of children's rights, a commitment Argentina made to the world and even enshrined in its National Constitution. A commitment that is betrayed daily.
