Couple things here.
First, corporate profits are aberrantly high for a number of reasons, none of which are likely to be permanent. John Hussman, an analyst whom I respect deeply, has a good discussion of this from the perspective of stock valuations, but the basic point is relevant here.

Second, while I agree that this is "the story" in a purely journalistic sense, it's important not to get too carried in discussions about relative income distributions and miss the forest for the trees, as it were.
Income inequality is not an informationally useful statistic on its own. Income inequality can be thought of as a measure of the strength of incentives in a system. Those incentives can be good or bad on their own. In 3rd world nations, income inequality is a reflection of the strong incentive to be corrupt and steal. In the closed system of Goldman Sachs, income inequality (among employees) is a measure of the incentive to achieve annual performance targets. In the context of the public education system, it is a measure of the incentive to achieve seniority and bureaucratic promotions. In startups it reflects the incentive to get acquired or IPO. Et cetera.
In the United States, when people say that income inequality is too high, what they're usually thinking is that the wrong things are being incentivized and rewarded. That's a fine discussion to have, and I would agree that certain industries [health care jumps immediately to mind] suffer from deep and severe incentive problems that are reflected when you look at income distributions within those sectors.
But the problem is not the income distribution; it's the fact that income is being distributed unequally for the wrong reasons. That is the conversion people should be having.
