The idea of a wall on the southern border is one that has gone the the mind of the majority of the citizens of the United States of America. However, the facts remains clear that a wall will not be effective on the southern border because a border wall would be a social barrier, illegal immigration would not be stopped, drug flow would not be stopped, taxpayer money would be wasted, and immigration reform will not be enhanced. Donald Trump’s idea to build a “great wall” on the southern border will simply not work, and Americans need to be more focused on uniting their country with others-- not building literal walls between them.
