Today, in a tweet supporting the candidacy of Roy Moore for the US Senate, Donald Trump said: "The last thing we need in Alabama and the U.S. Senate is a Schumer/Pelosi puppet who is WEAK on Crime, WEAK on the Border."
Trump's continues to insist that Mexicans are flooding into the United States in vast numbers and most are criminals.
For these reasons Trump is determined to build a wall along the Mexican/United States common border. This will be a sizable investment of taxpayer's money.
As with all investments facts matter: Get the facts wrong, an investor is sure to lose money.
First Fact: On Nov. 21, 2017, the Pew Foundation, Fox news and the Washington Post reported, "That from 2012 to the present, more Mexicans both legal and illegal were leaving the United States than arriving from Mexico."
Second Fact: A 2015 study by the National Academy of Sciences and replicated in March 2017 by the libertarian Cato Institute found that: "Immigrants from Mexico and other Central American countries are in fact much less likely to commit crime than natives." And "Illegal immigrants are 44 percent less likely to be incarcerated than natives."
With these facts in mind, Trump's border wall is going to be a very bad investment for the country he swore "I will faithfully execute the Office of President of the United States." "Faithfully" in this context I suppose means that he will fully inform himself of the issues at stake before he "executes" a measure and that neither he or any member of his family or friends would benefit from the action he takes.
