Even with donated funds, the government would be required to maintain it. Why waste money on a wall that has been proven not to stop illegal immigration. Private donations are good for communities with upper income residents, such as donations for schools, beautification, business reclamation. Studies have shown the walls are not reducing the number of illegal immigrants coming into the country. There are more important uses for donated funds. Schools would be my number one use. New buildings with upgraded technology are needed in every state.
