This is, no doubt, a well researched and compelling post. I enjoyed the flow, following the links between the events. In the end, a fine research work was accomplished and the words below, methinks, should be written in gold:
It seems to me that building a wall just leads to people going around, over, under and through it. With the U.S.'s low unemployment rate of 3.9%, it just might not make sense to wall the U.S. in, when it might be looking for outside labor like it has in the past..... only to boot them when done with them?
