Any bipartisan deal to reopen the federal government and deal with DACA would have to legalize some of the DREAMers, increase border enforcement, amend the diversity immigrant visa program, and fund the construction of a border wall. Democrats have compromised on the border wall but they are still only going to fund about half the lowest estimated cost of about $8 to $10 billion. There is a way to fund construction of the border wall without using taxpayer money or for Congressional Democrats to allocate a penny more than the $8 to $10 billion that they are considering: The Border Wall Investment Visa Program (BWIVP).
As proposed here, this new program would take 10,000 green cards from the 50,000 currently allocated diversity immigrant visa program, or whatever successor program Congress creates to replace it. Congress could then shift those 10,000 green cards to a new immigration category called the Border Wall Investment Visa Program (BWIVP), which would auction them to the highest bidders each year. Under such a system, each green card could sell for at least $100,000 and potentially much more. At that high of a price, the BWIVP would raise $1 billion each year to fund the construction of a border wall without raising taxes. Congress should write into law that all funds raised through the BWIVP should automatically go toward wall construction and maintenance. Of course, Congress could also auction more or fewer than 10,000 green cards a year but this is a nice round number for the purpose of an example.
The $1 billion a year raised through the BWIVP would fund the construction of an additional 46 miles of fencing a year without taxpayers spending a dime, if the recent estimated cost of replacing the border fence were any guide to the costs of future construction. An extra $1 billion a year raised through a BWIVP would significantly stretch the eventual length of the wall relative to other funding options. Nobel Prize Winning economist Gary Becker proposed a $50,000 price per green card in 2011 but suggested selling a million annually. Prices will have undoubtedly risen since then and the BWIVP would only auction 10,000 green cards a year, so the price for each one would be higher.
