Why did people resent immigrants coming in to the us?

People resented immigrants coming to the U.S. for several reasons, including economic competition, cultural differences, and social tensions. Many native-born citizens feared that immigrants would take jobs, drive down wages, and strain public resources. Additionally, cultural and language barriers often led to misunderstandings and a perception that immigrants were undermining traditional American values. This resentment was often fueled by broader economic instability and social anxiety during periods of high Immigration.
