I think a lot of this kind of stuff is also being manufactured for shock value. My dad used to have teenagers yell "go back where you came from" at him when they were mad at him when I was a kid in the 80s. He is mainly British and German and my family has been here for three generations minimum (that's the shortest time - we have some ancestors here much longer).
We have no real evidence the caravan was formed organically by people fleeing violence and corruption. Some may have been, but if they are legitimately fleeing they should've asked for asylum either at the US consulate or in Mexico. Storming our borders is not the way to flee corruption.
The dream of being able to succeed based on merit (meaning, you do a job well and you'll be sought after to do it regardless of who you are) and not on unearned factors such as race, religion or class is still alive and well here so long as the government is not allowed to begin putting it's thumb on the scales of justice and handicapping people who are perceived as having "too much privilege".
