“Children in unlawful immigrant households receive heavily subsidized public education. Many unlawful immigrants have U.S.-born children; these children are currently eligible for the full range of government welfare and medical benefits. And, of course, when unlawful immigrants live in a community, they use roads, parks, sewers, police, and fire protection; these services must expand to cover the added population or there will be ‘congestion’ effects that lead to a decline in service quality.
In 2010, the average unlawful immigrant household received around $24,721 in government benefits and services while paying some $10,334 in taxes. This generated an average annual fiscal deficit (benefits received minus taxes paid) of around $14,387 per household. This cost had to be borne by U.S. taxpayers.”May 6, 2013
