Its very purpose is to restrain the efforts of the majority to use government to destroy or undermine the social, political, and cultural differences of weaker groups. In addition, the American economy and culture has greatly benefited by the diverse contributions of immigrants. Each year the production and purchasing of goods and services rises and stimulates economic growth. Many immigrants have been highly talented and cutting-edge leaders within business, research, and industry. The field of computer technology is a perfect example.
Immigrants also take important jobs that are unskilled and low paying, such as migrant picking.
The overwhelming number of Americans shun such work or would accept it grudgingly. No doubt there are concerns with population growth. But the fact remains that women in the United States are on average having only 2.0 children, a figure just below the replacement level. Such an aging American population is going to need employed immigrants to sustain their economic and medical needs. Of equal importance are the many ways that immigrants have added to the richness of culture within the United States.
