I only want to address two points, because the military compensation issue is a rabbit whole upon which we will never agree. So, two points:
This is particularly instructive and points to exactly what I am saying about not viewing with total disgust those less fortunate. If your comparison is with animals and bugs, that says a lot about your entering attitude with regard to the poor. My point as to race and ethnic breakdown is that the problems and challenges of the bottom income brackets, particularly the poverty stricken, transcend those particular categories, and worrying excessively about what percentage happen to be latino is less then helpful. Grinding poverty may indeed by accerabted by culture failures and norms, but those same failure are present in Appalachia as well as Harlem. If I roll my eyes at your primary issue, which seems to be pointing out the ethnic breakdowns, its not "living in ignorant bliss" so much as believing that the racial breakdown numbers aren't particularly instructive.
I left those out because I have no idea what percentage smoke, drink, or use drugs. I was unwilling to make gross generalizations. I am betting that they don't spend $20 a bottle though.
