Final answer:
Rodriguez proposes that America should consider the Mexican model of assimilation, where intermarriage has created a cohesive culture, in contrast to the multicultural approach seen in the U.S.
Step-by-step explanation:
The Mexican model that Rodriguez proposes America should consider is one of cultural assimilation and melding, in contrast to a multicultural 'salad bowl' approach. In Mexico, there has been a significant amount of intermarriage among Spaniards, indigenous populations, and Africans, leading to a cohesive Mexican identity. Rodriguez points to the higher rate of these intermarriages as a primary difference between the United States and Mexico, arguing that in Mexico the various ethnic and racial groups have blended to create a unified culture. This blending is analogized to the process of making a burrito, with a variety of ingredients rolled into one creation. This model contrasts with the United States, where a variety of ethnicities coexist, ultimately contributing to both cultural innovation and ethnic tension.
