The US itself is an economic entity, and every aspect of life today is determined by economic status/class. The US went to the extreme of stripping our poor of the most basic human rights (UN's UDHR) of food and shelter. We know that not everyone can work, and that there aren't jobs for all, but we simply don't care.
What matters most to people is whether or not they have the means to keep their families together, housed and fed. Many don't. Even liberals have disappeared them from the discussion. The great majority of very poor are white, but I can assure you that the hell of US poverty today is the same regardless of skin color. The fact is that people of color don't know white poverty exists, and white people pretend it doesn't. On the rare occasion that poverty comes up, we refer to poor people of color as "disadvantaged," and poor white people as "white trash," and treat them accordingly.
Could anyone imagine that this has had no impact on the US overall?
