I know this would probably make all sorts of libs (and maybe others) angry when saying something like this, but it is likely time to start confronting the issues surrounding why these hordes from Central America and Mexico try to come into the United States like this. The culture of American drug abuse, which in turn gives money to the drug lords who brutally rule over these areas is likely that major cause, in addition to corrupt and incompetent political leadership there.
It’s one thing to build a wall, granted, but you are likely also going to have to help clean up the bad neighbourhood in order to keep it from spreading into yours. FDR recognized this regarding World War II over the vociferous objections from many who thought the U.S. should stay out of European wars (in spite of his other policies that do have legitimate reasons to be criticized). And IIRC, FDR as a young man was routinely looked down upon by his upper class peers for the work he and Eleanor did in the slums of NYC.
I agree, the drug culture in the US - as well as gang culture, immorality culture, the rotten educational system (commiepuke propaganda for more than 25 years) etc - is a rot that needs to be addressed if we are to continue as a country.
