Public opinion on Obamas' "Buffett rule" concept 2012

This graph shows a poll regarding the American citizens' opinion on the "Buffett rule" concept brought up by Barack Obama. 52 percent of Americans say that capital gains and dividends should be taxed at the same rate as income earned from work, according to the poll.

According to Wikipedia, the Buffett Rule is a tax plan proposed by President Barack Obama in 2011 to alleviate income inequality in the United States between the top 1percent of Americans and the remaining 99 percent of Americans, due to the disproportionate income growth in the 1 percent- group as compared to the 99 percent- group. The tax plan would apply to individuals earning more than 1 million U.S. dollars per year; this comprised the top 450,000 of Americans by income when the rule was proposed.
The plan is named after American investor Warren Buffett, who publicly stated in early 2011 that he disagreed with the rich paying less in federal taxes, as a portion of income, than the middle class, and has voiced support for increased taxes on the wealthy. It would implement a higher minimum tax rate for taxpayers in the highest income bracket to ensure that they do not pay a lower percentage of income in taxes than less-affluent Americans.
