Many stuck near the bottom

From Joel Kotkin of the OC Register:

Declining prospects for upward mobility, and the simultaneous social inequality, are the existential issues of our time. The percentage of adults who believe things will be better for their kids is at its lowest point in 30 years, with a majority now saying upward mobility for the next generation is not likely. The kids, God bless them, are still far more optimistic.

Despite President Obama's occasional class-warfare rhetoric, this gap has widened significantly under his watch; the top 1 percent of earners garnered more than 90 percent of the income growth in his first two years, compared with 65 percent under George W. Bush. But the problem is more extensive than one or two administrations. Most Americans' incomes have stagnated for almost a quarter century.

So under a Democrats regime, the rich have gotten richer and the poor have gotten poorer.

Why is this not the lead story everywhere?
