SAN FRANCISCO (MarketWatch) -- President Barack Obama blasted Wall Street for worsening the economy's downturn and promised to make financial markets more transparent and accountable.

In his weekly radio and Internet address Saturday, the president applauded the House of Representatives for passing sweeping financial reform legislation and said the economy is recovering from the "irresponsibility" of Wall Street firms that "gambled on risky loans and complex financial products, seeking short-term profits and big bonuses."

It was "risk management without the management," Obama said. "Their actions, in the absence of strong oversight, intensified the cycle of bubble-and-bust and led to a financial crisis that threatened to bring down the entire economy."

Obama also blamed an "era of easy credit" for some of the excesses. "Millions of Americans borrowed beyond their means, bought homes they couldn't afford, and assumed that housing prices would always rise and the day of reckoning would never come," he said.

"It was a disaster that could have been avoided if we'd had clearer rules of the road for Wall Street and actually enforced them," the president said.

The House on Friday narrowly approved the most comprehensive financial industry regulations since the Great Depression, including new restrictions on the biggest banks and the Federal Reserve. The legislation also would create a Consumer Financial Protection Agency to oversee mortgage, credit card and other banking products. Read about the House vote.

Obama urged the Senate to act quickly on its own financial reform proposals to ensure that the "risky dealings that sparked the crisis would be fully disclosed and properly regulated." And he criticized Republicans and financial industry lobbyists for blocking efforts to mandate tougher rules.

In an interview with CBS' "60 Minutes" program scheduled for broadcast on Sunday, Obama condemns bankers for taking government bailout money and are now collecting handsome bonuses.

"I did not run for office to be helping out a bunch of fat cat bankers on Wall Street," Obama said, according to excerpts from the interview released Saturday.

"What's really frustrating me right now is that you've got these same banks who benefited from taxpayer assistance who are fighting tooth and nail with their lobbyists ...up on Capitol Hill, fighting against financial regulatory control," the president said.

In the Republican address on Saturday, U.S. Rep. Marsha Blackburn of Tennessee focused on climate change and the international summit that Obama is slated to attend on Dec. 18 in Copenhagen.

Blackburn criticized Democrats for wanting to "impose a 'cap-and-trade' national energy tax, a bureaucratic nightmare that would make households, small businesses and family farms pay higher prices for electricity, gasoline, food and virtually every product made in America.

"Just think of what will happen to small businesses and manufacturers hit with these skyrocketing energy bills, especially when nations like India and China don't agree to these mandatory emissions limits," Blackburn said. "With Americans already facing double-digit unemployment, there could not be a worse time to unilaterally disarm our engines of job creation and economic growth."

Blackburn said the Republican energy plan, in contrast, doesn't "tax people out of their house and home" and puts "every clean, responsible energy option on the table so we can create jobs, ease the strain on family budgets, and clean up our environment."
