Why do you think criollos and mestizos resent the peninsulares in new Spain?

Criollos and mestizos in New Spain resented the peninsulares primarily due to social and economic inequalities. Despite being born in the colonies and often holding significant local knowledge and resources, criollos faced discrimination and were frequently denied high-ranking government positions, which were reserved for peninsulares, or those born in Spain. This exclusion fostered feelings of frustration and resentment, as both groups sought greater autonomy and recognition of their contributions to colonial society. Additionally, the peninsulares' perceived elitism and cultural superiority further fueled tensions between these social classes.
