If remittances from the United States slowed down, it would have a significant impact on Mexico's economy. Remittances are a major source of income for many Mexican families, and a decrease in remittances would mean a decrease in the amount of money available to them. This could lead to an increase in poverty and a decrease in the standard of living for many people in Mexico. Additionally, it could lead to a decrease in consumer spending, which could have a negative effect on the Mexican economy as a whole.
