Probably an insane thought, but perhaps the 'us vs them' attitudes in current political parties and stances may be having an effect? Maybe people are too distracted by the whole theism vs atheism/religion vs religion arguments, the complaints about sexism/racism/transphobia/etc or general debates about whether things like abortion should be legal or not. Maybe people are being sidetracked too much by party politics and internet debates to actually do anything about income inequality. Or maybe as said before, the various other changes have decreased crime rates so much that even an increase in it due to this inequality is barely noticeable. If exposure to lead was really tied to crime rates, perhaps the huge drop off there simply masked everything else.
