FWIW - I think we have an immigration problem; however, the right has a bigger problem with this so - called "illegal immigration" issue. You're on the right track with this train of thought, but you need to have more facts. Let me present a few for you:
The Center for Immigration Studies, Federation for American Immigration Reform (FAIR), NumbersUSA, and about a dozen non-profit anti-immigration non-profit corporations were founded and / or financed by ONE man. His name is John Tanton. Little is written about him except in Wikipedia and the SPLC. Personally, I hold the SPLC in as little regard as I do organizations like CIS and FAIR. Still, the SPLC has not so nice things to say about Tanton. According to Wikipedia:
"According to
CNN, Tanton "has openly embraced eugenics, the
science of improving the genetic quality of the human population by encouraging selective breeding and at times, advocating for the sterilization of genetically undesirable groups."
[12] Tanton wrote a paper in 1975 arguing for "passive eugenics" whereby child-bearing would be restricted to those between the ages of 20 and 35.
[13] He also founded the pro-eugenics organization, the Society for Genetic Education (SAGE)

The
Center for Immigration Studies (
CIS) is a non-profit organization and think tank
[3] "that favors far lower immigration numbers and produces research to further those views."

Founded in 1985 as a spin-off from the
Federation for American Immigration Reform (FAIR)"

In the above link, it mentions a man by the last name of Paddock - not a very common name. Wonder if he was related to the Las Vegas mass shooter???
Anyway, in the good old days, before FAIR, CIS, etc. Tanton was doing research used by David Duke, the former nazi party supporter who founded his own version of the Ku Klux Klan. For whatever reason, even Politifact says that the SPLC only has papers stating Tanton corresponded with white supremacists and all the negative reports about Tanton are based upon old relationships. I don't like Politifact, but in all fairness they left out a key piece of information:
"He (Tanton) introduced key FAIR leaders to the president of the
Pioneer Fund, a white supremacist group set up to encourage "race betterment," at a 1997 meeting at a private club. He wrote a major funder to encourage her to read the work of a radical anti-Semitic professor — to "give you a new understanding of the Jewish outlook on life" — and suggested that the entire FAIR board discuss the professor's theories on the Jews."

The Pioneer Fund seems to be continually associated with David Duke:

My point to you is that if not for neo nazis and proposed socialist solutions, the build the wall effort would implode on its own. What amazes me is that so many in America pretended to despise someone like Bernie Sanders, but when it comes to that damn wall, the build the wall guys would perform a sex act on good 'ol Bernie if he was a swing vote in favor of the wall.
The sources the build the wall guys rely on is purely political propaganda socialism with little basis in fact. Few people are pointing out the neo - nazi, National Socialist founded organizations that are providing the rhetoric and talking points spewed by Trump supporters in favor of the wall.
