A positive change is that Americans love the Mexican food and their opinions are good and also their feedback. Americans see the Mexican food restaurant as a chain daily meaning they go daily to eat Mexican food and that helps them economically because that’s the only good job they can get so for them is a good job.
A negative issue is how they see us how we act how we talk how they make us look bad the rumors they make Mexicans look bad how they spread rumors they don’t see Mexicans as a good role model they see how Mexicans do illegal jobs and they see us a bad people. And they will still make us look bad because Mexicans have a bad reputation and that makes still look bad there's mostly Mexicans who get fired from work.
