Horn honking, thumbs-ups and high fives from passersby flooded downtown Brentwood on Tuesday as members of Moveon.org gathered in front of the Bank of America building to demand that the wealthiest 1 percent of the population start paying their fair share.

“Today is about raising public awareness of the inequality in taxes,” said Chris Flores, organizer of the event. “One percent of the population in this country has the vast amount of the wealth and yet they are paying far less of their share than they should.”

The rally was part of a nationwide effort called the Tax the 1% National Day of Action, held – fittingly – on tax day. And in downtown Brentwood, the dozen or so protestors raised their picket signs inscribed with messages that read “We are the 99%” and “Make Them Pay.”

Flores said the group chose to gather in front of Bank of America on First Street because the corporation as a whole is one of the most egregious offenders when it comes to paying taxes. According to Flores, Bank of America owes billions of dollars in outstanding taxes.

The peaceful protest came on the heels of a recent 99% Spring Training event held at The Game Sports Pub ’N Pizza in Brentwood, part of a nationwide effort to train 100,000 residents how to stand with the 99 percent in nonviolent actions to promote change.

And Flores believes it’s a movement whose time has come.

“Over the last year, we have seen the greatest rise in progressive activism in generations,” he wrote in a recent press release. “From the protests in Wisconsin to actions targeting the Keystone pipeline, Occupy Wall Street to Move Your Money, progressives stood up, took to the streets, took action and changed the debate in the nation. 99% Spring will train the country back for the 100%.”
