For every illegal migrant household that leaves the United States under Trump’s plan, Americans would recoup nearly three-quarters of a million dollars ($719,350), according to 2010 data collected by Heritage scholar Robert Rector. …
Illegal migrants cost U.S. taxpayers a net total of nearly $100 billion annually, concluded a 2010 investigation by the Federation for American Immigration Reform.
The 2010
report calculated the total contributions (mainly taxes) generated by the illegal migrants, and then subtracted the cost of taxpayer aid to those migrants. The aid includes education, subsidized housing, food stamps, tax credits, medical expenses. Overall, the report found illegal migrants cost taxpayers a total of $113 billion a year. The report then “accounts for taxes paid by illegal aliens [which is] about $13 billion a year, resulting in a net cost to taxpayers of about $100 billion.”
Under the Trump plan, that spending could be used to reduce taxpayer spending.
