So when you start to wonder, "hmm, I wonder why housing is so expensive relative to my income", or, "hmm, I wonder why that policeman gave me a $400 ticket for 'speeding'", or, "hmm, I wonder why those federal agents are killing children in Waco", or, "hmm, I wonder why no bankers went to jail for fraudulent mortgage practices in 2008"...
... I mean, if you ask yourself these questions, and you tell me that these things are happening because we elected people to do these things, then I don't precisely know where you got that notion.
