Poll: 55 percent see inequality as big problem

As the Occupy Wall Street protest enters its seventh week, there's new evidence that Americans have grown increasingly concerned about inequality.

Fifty-five percent of likely voters surveyed by The Hill newspaper said they think income inequality has become a big problem for the United States. Nineteen percent said it's somewhat of a problem, and 21 percent said it was not much of a problem, or no problem at all.

It's not just those on the lower end of the ladder who are concerned. Sixty-five percent of those making $100,000 or more said inequality is either a big or somewhat big problem.

In addition, two-thirds of likely voters said they think the middle class is shrinking. Just 14 percent said it's staying the same size, and 14 percent said it's increasing.

A report released last week by the Congressional Budget Office found that the richest 1 percent of Americans have done far better than everyone else over the last 30 years.
