The group held up signs with messages like: "Tax inequality is bankrupting America."
They said big corporations continue to collect big tax breaks while the country struggles to balance the budget.
One of the organizers, the North Carolina AFL-CIO, said working families and middle class Americans are paying their fair share while many corporations and the rich are not.
"It's completely unfair that here in North Carolina low income taxpayers pay a third more of their income than the wealthiest tax payers, and you have corporations like Bank of America, FedEx, Duke Energy, not paying anything at all, and we're in a revenue crisis. We need more monies for our schools and public services and we think the richest folks should be paying their fair share," offered MaryBe McMillan with the NC State AFL-CIO.
Some state leaders have said offering corporations tax breaks helps lure them here, or encourages them to expand in North Carolina - helping to create jobs and helping the economy.
