People in American ghettos do express their opinions online, but the upper classes and special interest groups have much more ability to construct and influence the dominant narratives. So one should always question whatever is the prevailing wisdom surrounding lower class Americans. For example, in the 80s and 90s it was thought that a punitive criminal justice system and a draconian war on drugs was what they needed. Turns out, retrospectively, that was probably not an optimal approach and most people nowadays want to ratchet down the war on drugs.
