(CNN) - As procrastinators rush to file their 2011 tax returns by the Tuesday deadline, a new poll shows more than two-thirds of Americans believe the revenue system benefits the wealthy while being unfair to average workers.
In the CNN/ORC survey, 68% of respondents said the current tax system benefits the rich and is unfair to ordinary workers, compared with 29% who disagreed with that view. Overall, 50% said the federal income taxes they paid were about right, with 45% saying their taxes were too high and 3% answering their taxes were too low.

Throughout the 1990s, more than six in 10 Americans generally said their taxes were too high, but after the tax cuts proposed by President George W. Bush went into effect, that number dropped to the high 40s and has stayed in that range since.
Political and generational divisions exist in how Americans view their taxes. Some 53% of Republicans say their income taxes are too high, compared with 41% of Democrats. Among Americans who identify as independents, 44% say they're paying too much in income tax.
Age also matters - the youngest and oldest Americans don't think their taxes are too high, but Americans between 35 and 65 think that way. Among 18-34 year olds, 41% say their taxes are too high, compared with 51% for Americans aged 35-49 and 51% for those aged 50-64.
When polling those 65 and older, 36% said their income taxes were too high.
That generation gap may be better understood as a paycheck gap or salary gap - younger Americans, who tend to have lower-paying jobs, and seniors, who tend to be on fixed incomes, may see less of their household income gobbled up by taxes, compared with workers in their peak earning years who likely feel a bigger tax bite and respond accordingly.
The poll was conducted for CNN by ORC International from Friday to Sunday, with 1,015 adult Americans, including 910 registered voters questioned by telephone. The survey's overall sampling error is plus or minus 3 percentage points.
