Paul Volcker, former head of the Federal Reserve Board and an Obama adviser, also joined the session at a community college in Palm Beach County, ABC News reported.
"This has been a long time coming, and the warning signs have been very clear," Obama said of the economic crisis. "But while President Bush and (Republican presidential nominee) Senator McCain were ready to move heaven and earth to address the crisis on Wall Street, President Bush has failed to address the crisis on Main Street -- and Senator McCain has failed to fully acknowledge it. Instead of common-sense solutions, month after month, they've offered little more than willful ignorance, wishful thinking and outdated ideology."
Obama also said that his plan to offer tax credits to people who do not pay income taxes is not socialist since those people pay Social Security taxes.
Florida is the largest of the states likely to be in play on election day. Obama went on to Miami, where thousands of people gathered for a rally.
