So bripat, you are wrong about how 40% of illegal immigrants enter the country. But that's ok because 60% is still a barely passing grade.
Obviously you don't know what you meant by " close" the border so let's just talk about what would be most effective in limiting the number of people entering the country illegally.
More fences or walls, border monitoring equipment and guards is a fools errand. It would cost billions and could easily be circumvented but for far less we could broaden the use of the E-Verify system so that every employer would have to use it. This would exclude the vast majority of people here illegally from employment, which by the way is already illegal.
To refrain a favorite of the right "why don't we just enforce the laws already on the books?"
If people can't get jobs they will not come. This is the number one reason that illegal immigrants give as their reason for coming here.
I never used the term "close," so that claim is absurd on its face.
If fences or walls are so "expensive," then why did five European countries put them up to keep out those muzzie savages? Why did Israel build a wall around the West Bank? Why is Saudi Arabia building a double fence along its border with Iraq?
The beauty of a wall is that once it's up Democrat politicians can't make it disappear with the stroke of a pen on an Executive Order. If limiting illegal border crossings to zero required 50,000 personnel without a wall, it would require on 5,000 personnel with a wall.
The people who argue against the wall are all open-orders traitors who want to flood this country with illegals. That includes you.
We're building a wall, and we're also going to enforce E-verify, and we're also going to close all the sanctuary cities, so go suck on it.
