I am looking for factual information re: history of the laborers who
were involved in constructing the U.S. - Mexico border wall. 
Interested in who they were / are.  Interested in the technologies
(barbed wire...cement....steel).  Interested in communties
(families...) which directly benefitted from this wall construction
industry.

thank you,

Apache, that is certainly one of the most interesting questions I have
seen in some time, though I certainly cannot help you.  I really don't
understand which wall you refer to, since there are a number of places
between US and Mexico that have walls, and I had always assumed they
were different projects.

By the way, a few months ago, I heard on Fox News via satellite in my
friend's hospital in Mexico they were talking about making another
wall, in the Arizona area.

The Doctor laughed and laughed, and said, "You can be sure it will be
built mostly using illegal workers."  I thought that was funny, too.
