What explains why why immigration can lead to a decrease in wages?

Immigration can lead to a decrease in wages primarily due to the increased labor supply that comes with an influx of workers. When more individuals compete for the same jobs, especially in low-skill sectors, employers may lower wages since they have a larger pool of applicants to choose from. Additionally, if immigrants are willing to accept lower wages, this can further drive down compensation for all workers in that labor market. However, the overall impact on wages can vary depending on factors like the skill levels of immigrants and the economic context.
