Matt Levine does a great job of explaining scaremongering from the media (lately, mostly from the NYTimes) about Wall Street.
My favorite is the Goldman Sachs aluminum "scandal" from last year: http://www.bloombergview.com/articles/2014-09-03/the-goldman...
There's a lot of bad stuff that happens in finance, but we shouldn't be whipping out the pitch forks every time someone makes an accusation.
