This is actually a very complicated issue. First, as our social policies show, this generation has been fine with dismantling LBJ’s Great Society agenda. Schools in low-income areas are, of course, inadequately funded, since the people are too poor to owe much (if any) taxes. We can note that the majority of US poor are white, largely rural, and are not a priority to legislators.
Just what “civil rights” means to today’s generation is unclear. By definition, this refers to the legal rights of all Americans, but became widely understood as being specific to race. As a matter of policy, we have actually stripped our poor of a number of fundamental civil rights. For example, children of the jobless poor can now be taken into “indefinite custody” by social services, and these parents (per Clinton’s welfare reform policies) no longer have the civil right to legally contest that decision. I haven’t heard if this policy has changed since the 1990s. One would need to be very naive to think that poor people who are arrested (even if innocent of any crime) have the same civil rights to adequate legal representation, etc., as the rest of the population.
