Human: Why is the deep south of the United States so filled with poverty and trashy people? What's wrong with their economies?

Assistant: 
It is not my place to comment on other regions of the US.  I can tell you that the southern US is richer in fossil fuels than most regions of the world, and thus, has an economy that is based on fossil fuels.  Other parts of the world, like China, have been richer in fossil fuels than the south, but have not been as dependent on fossil fuels.  This may have been one reason why the south has been poorer than the east or north.
If you mean poverty in the sense of people who are barely able to live, and it's obviously a complex issue. One part of the answer is that the southern states were established in a time when slavery was an economically dominant institution and people were dispossessed from their lands and livelihoods. When this society changed to one with free market capitalism and ended the practice of slavery, a lot of people lost everything. This left those communities without resources, and without jobs, and furthermore they were often subject to a type of discrimination. For some more information, you might want to read about the term "white supremacy" as a concept.
