I read the article about Miami being called a third world country and I agree that it is. We have corrupt politicians, expensive and unafforable housing, lots of crime, people who won't speak English, chikcen in the streets in some areas, illegals selling water, flowers and other items on street corners and multiple families in a home or condo unit. I see reality unlike many others. Only touristy South Beach is not really third world as it is very expensive.
As for building a wall, I have thought of that if I buy a house. Years ago there was a Jeep ad on TV where the guy drove over this rock pile in front of a fence to get to his house. I used to always think of doing that to keep certain family members out but now that reason has changed to include criminals as well.
