What’s happened to America?

There was an empty building in my neighborhood the used to be a supermarket. Today I passed by it and there was a sign on the building; “La Plaza Marketplace.” I felt I was in Mexico and not America. Under the name was an internet address and when I got home, I put in on my computer and this is what came up to sell spaces in the business;

Located in a low crime, moderately affluent area,
adjacent to Hispanic/Latino neighborhoods

This describes what the neighbor used to be except “adjacent to Hispanic\Latino neighborhood.” When the area was flooded with Hispanics and crime the Americans moved out.
I have seen it go from a low crime area where I raised my children to a place that is referred to as the “jungle.” Garbage spewed around, graffiti, gangs and other crimes and it is now 90% Hispanic and so are the school which has a waiting list for kindergartens.
I will be moving also and it is not because of Hispanics but because of crime.
The apartment complex I've lived in for years had two maintenance men that were americans. Now they are Hispanic and all the work done on the complex is done by Hispanic. That is because they bid lower for the contracts. The complex is also owned by the city. I can't begin to describe how the complex has changed.
