I'm reading your links, so don't view this is a lazy retort. But I keep feeling that this two part video from Jon Stewart, Warren Buffett Vs. Wealthy Conservatives and The Poor's Free Ride is Over, speaks to your point of the "poor are getting richer."

And as for your incredulity at the fact that the rich get richer at the expense of the poor, if it's not an outright theft, though lord knows some folks would argue that, it's at least that capitalists routinely overestimate how much of their wealth was a result of their individual ingenuity rather than a combination of their individual ingenuity, the privileges and opportunities afforded them by former generations agitating for a more equitable and fair society, and public investment into roads, hospitals, and a more educated workforce, the backs of whom break for the profit of those employing them.

I'd like to see a little more hand-wringing when Oil Corporations receive $37 billion in tax subsidies in 2014 alone or when Corporate tax deductions for executive pay cost the US government $30.4 billion in lost revenue over the years 2007-10. Collect more from the poor? Jesus. "That's the problem with the poor... they still have some of their skin left."
