Marchers from the Occupy Wall Street movement, allied with other groups, walked through Manhattan's East Side past wealthy residences.
Marchers stopped outside of apartment buildings thought to be residences of media mogul Rupert Murdoch, banker Jamie Dimon and oil tycoon David Koch.
The marchers expressed concern about how much less the wealthy will pay - and who would be harmed because of those lowered tax revenues when New York's 2 percent "millionaires' tax" expires in December.
The march was the first in the weeks since the protest began that identified specific people as being part of the 1 percent of the wealthiest Americans the demonstrators say are enriching themselves at the expense of others, through the influence of corporations and corporate culture on American society.
Protesters have been camped out for weeks in lower Manhattan's Zuccotti Park, near Wall Street, saying they're fighting for the "99 percent," or the vast majority of Americans who do not fall into the wealthiest 1 percent of the population.
Their causes range from bringing down Wall Street to fighting global warming. The movement gained traction through social media, and protests have taken place in several other cities nationwide.
