The United States wall.

On the U.S. talk shows they are now talking about a wall between the U.S. and Mexico ! Would it go from the Gulf of Mexico to the Pacific Ocean ? Would it be longer than the Great Wall of China ? Would it be over 30 feet high like the one in Israel ? Should we be investing in cement stocks and SNC Lavalin ? We do not intend to be critical either way; in Mexico many of those who want to work can't get a job. In the U.S. there are many who need workers and there are not enough Americans available.
