Absolutely perfect example of liberal hypocrisy.  One hears nary a beep from the liberal masses about this problem and its potential causes and solutions.  No liberals expend their energy on "Russian Collusion," Trump's useless tweets (whatever a tweet is), and other purely partisan nonsense issues.  Moreover, liberals lead the pack in enacting building restrictions and the like to keep the "undesirables" away from their neighborhoods and limit construction of low income housing on cheaper land outside the "urban growth boundary."  Gotta love the liberal hypocrisy.
