It's a waste of money. Most illegals come here legally. An unmanned, unmonitored wall (cause CBP doesn't have nearly enough manpower), is nothing more than a speedbump on your way to gaining entry into the United States. The money would be better spent aggressively prosecuting people that entice, and hire illegals.
I agree with your stance on punishing the employers of illegal immigrants. That would de-incentivize the desire to come to America illegally. But... without a wall it is pointless. Yes, people here on a visa overstay their visit, but at least we have an idea of who those people are. Allowing open boarders allows anybody to come across freely, and by doing so there is no way to tell who has come across. A wall is very much needed.
