Not much to add to that, only a short list
- Trump and Clinton both want to build a wall; it’s not really an issue, so long as Congress approves it
- The type of walls that will be built would be more state of the art compared to the ones of a castle or house; more similar to military bases that can detect underground activity, have surveillance (infrared and otherwise), etc
- Even if the wall is not 100% affective, it may still serve a purpose if it prevents, helps to deter, and/or slows down any would-be offenders
- A wall could also serve an economic purpose as a public works project, to provide many with mid-term jobs similar to FDRs plan, though not as grandiose
- The wall is only important to control immigration, especially what is considered illegal; there’s an estimated 10s of million people illegally in the US (actual number unknown) and even if all are accepted as US citizens, what happens in 5–10 years when there are millions more? What prevents the problem from continuing to happen? Is the precedent to keep allowing everyone?
- The US immigration process is important to ensuring the integrity of the US system, its culture and beliefs. Legal immigrants have a great understanding of the heritage, sometimes better than native born; whereas illegals may not know it as well. This presents a long term problem when illegals are bearing children that can vote.
- A few thousand illegals isn’t as much an issue, but a few million certainly could have an impact on an election and the future direction of a nation. Consider the fact that illegal immigrants are already starting their citizenship on a bad foot, where they can get ahead by doing things above the law — that’s not a good thing for people to subconsciously know. It’s not good when those people have voices
But a wall or protection of some form is inevitable.
