The Economics of Wall Building

The National Academies of Sciences, Engineering and Medicine (NAS) estimates that the average cost to taxpayers of an illegal immigrant is $75,000  --  taking into account taxes paid and the cost of providing benefits such as education and health care. The estimated cost of completing the Southern border wall is around $20 Billion. Mathematically that means that if the wall prevents only 260,000 illegals from entering the country it will have a positive ROI.

Since Trump was elected, the number of illegal border crossings has dropped significantly (some estimates suggest a 50% reduction) just in response to the threat of building the wall and stricter enforcement of existing immigration law.  It seems rather likely that The Wall could be one of those rare government expenditures with a positive return on the investment.
