Group advocates raising taxes on wealthiest Americans

"After 50 years of tax cuts by Kennedy, Reagan and Bush II, the middle class is paying the same share of income as they did in 1960," said Chuck Collins, co-founder of the group. "The richest 3 percent have gotten the gargantuan share of tax cuts."

The group cites a recent Quinnipiac University poll that found 60 percent of Americans across political parties favor an increase of income taxes on those making more than $250,000 a year. 

On its Web page, the group says it's calling for the Bush tax cuts to expire because "we feel it's time to rebalance the economy so that it works for everyone, not just the wealthy." 

"Our country is facing unprecedented economic challenges right now: We all need to pay our fair share to resolved these issues and make our long overdue investments in education, health, energy and infrastructure."
