Once you construct your precious wall, and immigrant smugglers respond by tripling their fees and building tunnels underneath it (or simply leasing drug tunnels that are already there) to stay in business, you can admit you were wrong, put aside simplistic solutions and think more deeply about how to deal with illegal immigration.

To show there are no hard feelings, I’ll even recommend a company with some expertise in that area. Let’s see. Where did I leave that business card? Oh yeah, here it is.

President Trump should call the Golden State Fence Company in Riverside, CA. Launched in 1984, the company—which has contracted with the U.S. government to build fences on the U.S.-Mexico border—at one point had as many as 750 employees and generated annual revenue of about $150 million.

Oh wait. There is no more Golden State Fence Company. The outfit is now called Fenceworks, Inc. That’s because the Golden State Fence Company was busted in 1999, 2004, and 2005 for hiring illegal immigrants—to build the fencing that was meant to keep out illegal immigrants.
