WHY WE BUILD THE WALL

Somebody is trying to sell me a wall. The same way they sold my father and my brother a Vietnam. 
We need a wall like we needed Vietnam. I ain’t buyin’ it.

Interesting song I heard last year on the Old Prairie Home Companion show.
Anais Mitchel, from her 2010 opera, "Hadestown". There is a minute of chatter before the song.
