Just going to ignore that last statement. I do have to say the people on here who are arguing for a wall. First of all, no one is for open borders. 2nd of all, whether you are republican or democrat, as it exists now cheap, below minimum wage labor in the form of immigrants, picks our produce, plants our plants, work in factories, is used for domestic and maid service. The republicans who on one side of their mouth spouting anti-immigrant rhetoric, including taking American jobs, increasing crime, are on the other side HIRING these people to do these jobs. They KNOW they are immigrants. They know that if they truly wanted to stop illegal immigration, the way to do that is to have more strict enforcement of labor laws. What should we do about immigration? Increase the staffing for processing immigrants as well as for tracking throughout the system. Increase the number of work visas, for both skilled and unskilled workers. Have a legal realistic way that legal immigrants can become citizens, including dreamers, so they are motivated to work within the system and be good citizens. Employment is tracked, taxes are paid, and these companies ARE getting labor, except labor at the minimum legal wage. This helps American workers because it puts a floor on wages versus paying people "under the table". It protects immigrants because they have worker protections. It protects Americans because we can keep the immigrants we want, and process out the ones we don't. The only people it doesn't help are businesses who want to pay immigrants less than minimum wage and have no worker protections.
The things I am suggesting would cost less than a physical wall which is ineffective for the vast majority of how immigrants get into this country. According to experts a wall would do little to nothing about drug smuggling either.
There ARE small areas in urban areas where local law enforcement is asking for physical barriers to be beefed up and yes fund that. However for vast areas of desert, areas cutting through people's private property and reserves, no one in those areas is asking or WANTS a physical barrier, including law enforcement. "Build a wall" is a HUGE (metaphorically and physically) distraction to what the real world issues and solutions to immigration are.
