How do immigrants really affect the u. s. economy?

I literally just did a whole essay on this for my class, When working immigrants come into the United States they provide low cost labor, allowing companies to offer their products at a lower cost for everyone else, and immigrants also pay taxes when buying goods, helping cover medicare and other funds taxes go into, but they do create competition in work areas with natives without a college education, such as agriculture and construction, since higher paying jobs require education and strong communication skills.

from the conditions of the working class in england by friedrich engels,the main idea is :

silk

indigo  

rice

all the other answers are wrong
