How has illegal immigration impacted the U. S. economy? Also give an example if it has or has not.

Immigration in the U.S. has caused families who pay taxes( everybody) to pay for others who did not come in legally. Immigrants can come across the border illegally and apply for social security in which they get our U.S. tax money and get money for any immediate family they have. Hence, American citizens are paying for illegal immigrants who do not pay taxes.
