One of Trump's major pledges to his presidency was to build a wall between the U.S and Mexico. Although the wall would help to eliminate the amount of illegal immigrants that come into the United States from Mexico, there is nothing that can be done to eliminate illegal immigrants. Whatever the U.S does, illegal immigrants will still find a way to enter the country. Building a wall will only hurt the taxpayers even more.
Building a wall is estimated to cost anywhere between $4-$10 billion dollars. Trump has claimed that Mexico will pay for the wall, but Mexico's foreign minister stated Mexico will never pay for it. This means that the financial burden of the wall will be on the taxpayers.
The wall would be on the border between Mexico and the United States lying on California, Arizona, New Mexico and Texas borders which is about 2,000 miles. Since there is so much land to cover there is a variety of different types of land including beaches, cities, dessert dunes, mountains, flatlands, and bodies of water. The wall would have to be able to be sustainable for these environments. Which could also include repairing and maintenance to the wall, costing more money.
The wall would extend through territories that would possibly not be able to have a wall. Such as private property, national parks, Native American reservations and floodplains. Owners of private property might not allow their land to have the wall built upon, or could possibly ask for extra money from the government for compensation.
The wall itself would range in cost anywhere from $400,000 to ten million per mile. Depending upon which type of material used for the land. Additional costs would be electronic surveillance and border patrol. Places along the border that have a wall right now have still been known to have people illegal cross, using ladders, tunnels and ramps.
Illegal immigrants will still try to get into the United States even if there is a wall. The wall will only cost the tax payers billions of dollars plus additional money for maintenance and repairs.
