Of course.
I believe a fence is a valuable component in border enforcement.
But getting one erected would be little more than a symbolic gesture if the demand for illegal scab labor is not addressed.
"But getting one erected would be little more than a symbolic gesture if the demand for illegal scab labor is not addressed."
1) There is nothing wrong with symbolic gestures.
2) Its not the responsibility of society to meet the labor demands of business. Business's deprived of cheap labor are on their own. How did anyone do business in this country from 1920-1980 when we had almost no illegal immigration and very little (as a percent of population) immigration of any kind. How is that all the other countries of the world maintain their standard living without letting millions of poor Mexicans walked into their country every year?
3) Building a wall and securing the borders is a National security issue. Its something that can be done and while it wont solve the entire problem of illegal immigration it will be very helpful.
4) The idea we should NOT build a wall because it is not the "perfect" solution or will only solve "part" of the problem is absurd.
5) Lets start building the wall NOW! While the wall is being built, we can discuss all the other issues.
