I bet if Wal Street recruited Drug lords they'd would find the kind of smart, give no quarter leadership that executives admire.  (Only half kidding).   

You got it right, they do it to make money.   Just like we sometimes prostitute ourselves for the next promotion, or look past something 'small' if reporting it would get us in trouble.   Helping the kids obtain adderral for the ADD, (and get better grades)?, easy to find it's all over at work - down on Wall Street.

There's behaviors that I disapprove of that are accepted by those in poverty and parts of black culture that make me really uncomfortable.  We hate the promiscuity and unwanted children, but sex can be a moment of fun and pleasure for both people and it's free!  (at least in the short term).   Same in poor white rural Iowa/Oregon.  

Poverty does not give a crap about your skin color, but your skin color can add to the difficulty of being poor.
