Matt Yglesias isn't buying my story that skyrocketing Wall Street earnings—and the skyrocketing incomes of the super-rich in general—are basically coming out of the pockets of the working and middle classes:

I think what Kevin’s story keeps missing is a plausible causal account of how a tiny number of financiers have been able to hoover up money from the median wage earner....I can tell you a story about how a tiny number of financiers have been able to hoover up money from the broad class of rich people in the 80th-99th percentile who own the bulk of the financial assets in the country by swindling them. I can tell you a story about how a tiny number of financiers have been able to hoover up money from the broad class of rich people via the income tax and “bailouts.” But the median wage earner seems harder to me.
