This puts to question if a wall would even be helpful. If people already can cross the existing wall by going underneath them then it shows that spending more than $5 billion is not useful. Part of the issue that’s cannot be fixed is that there is infrastructure underneath that cities use to drain water but are being used to build tunnels as well. On the spot there are many ways to get around the wall, if one were to be built, someone could use a ladder, rope, tunnel, break it, or go through the ocean, and those are on the top of my head. I also read of an instance of people using cannons to throw drugs over the border. With all this said, if the government wants to decrease crime, or undocumented immigration, it is a worthwhile investment to make the immigration process easier or put money towards USCIS as a whole (since they self-generate money). If people were more willing to go through the process then as a whole the number of undocumented immigrants will decrease. However, many are seeking asylum or are desperate to move for a better life for themselves and their family so waiting 20 years is not an option for them. If the parts of the U.S border that do have a wall have shown many instances of not working, then it’s likely that a fully constructed wall won’t work as well. The money could be better spent in any other department.
