El número récord de encuentros con migrantes en la frontera México-Estados Unidos encubre la historia más importante

Los titulares enfocados en la cifra récord de 2,4 millones de migrantes encontrados en la frontera México-Estados Unidos durante el año fiscal 2022 encubren la historia más importante: Los flujos migratorios se han diversificado rápidamente más allá de México y el norte Centroamérica, y como resultado, las políticas de control migratorio son incongruentes con la realidad de hoy.
