Not a fan of Trump, but he was fought tooth and nail on his border plans and wall.
I don't know any Americans who have trouble with legal immigrants.
Illegals don't go straight to the fields - that's pretty racist, no? They head to cities where service jobs are.
Europe, Australia, New Zealand, Canada, and the United States would literally have millions show up if their borders were perceived to be open. (Maybe a million Afghani's alone) That is why they sent Harris to Central America and showed camera footage of planeloads being sent on planes back to Haiti.
Ask the European's and the Floridian's what happens when mass migration hits.
The wall was a pile of bombastic, divisive bullshit. It would take too long, cost to much and not actually solve the problem. It ceded US territory and required forced taking of land from citizens that live at the border. Importantly, the entire border doesn't need and shouldn't be "walled". Walls and other barriers are needed and useful in certain regions, especially near larger population centers on the border but not so in vast parts of the border. Plus it requires constant upkeep at a very high cost.
I support good borders and funding to enforce such and to build proper walls and other border enforcement elements as needed where needed. But in no way do I support Trump and his moronic "build a wall!" bloviating. That was political bullshit.
Illegal immigration always has many different elements, varying by country. For the US the most "known" illegal immigration is from Mexico and you really need to get past teh political bluster that uses it as a cudgel to get votes.
You say "Illegals don't go straight to the fields - that's pretty racist, no? They head to cities where service jobs are."
But you blow away reality with such a broad statement. There are many workers from Mexico that come to the US illegally and go straight to the fields or the slaughter houses etc. And there is nothing racist about that. There are also a lot of illegals that go to work in service industries in large metro areas. But from what I have read those tend to be ones that are living here longer term. One thing a "hard border" does it makes it harder for people to go back and forth. And the reality is that a lot of job seekers would like to just go back home and then come back to work as needed. They can't, so they are forced to stay, and that sets roots and that brings more as family members join (because most families prefer to be together).
This is one of the reasons why I think changes like I suggest are needed.
There is also a big difference between the transitory illegal labor form Mexico and illegal immigrants from distant nations (such as Haiti). Those need to be viewed and managed differently and the reality they cannot just go home. They are desiring only to stay (sometimes the desire is said to only be for a temporary stay but most all such situation has turned into a desire to stay permanently) and we cannot just take in all the world that wants that. We need sound policies and proper border enforcement for that.
And everyone needs to understand that we will see "pictures" that look distressing but with proper review and oversight and disciplinary action if needed, those pictures are just one of the tools to ensure we are managing our borders and immigration properly and safely.
