Why were immigrants often hired to work in a sweatshop?

Immigrants were often hired to work in sweatshops due to their desperate need for employment and lower wage expectations compared to native workers. Many immigrants faced language barriers and limited job opportunities, making sweatshops one of the few available options for earning a living. Additionally, employers exploited their vulnerability, often subjecting them to harsh working conditions and long hours for minimal pay. This reliance on immigrant labor helped fuel the rapid industrialization of urban areas during the late 19th and early 20th centuries.
