US President Barack Obama hammered Republicans on Saturday over their newly unveiled campaign agenda, calling the opposition party's economic ideas "an echo of a disastrous decade we can't afford to relive." In his weekly radio and Internet address, President Obama said Republican plans to roll back healthcare reform and extend Bush-era tax cuts for top US earners would not fix the nation's economic woes. President Obama continued that critique with his appraisal of the Republicans' "Pledge to America" plan. "It is grounded in (the) same worn out philosophy: cut taxes for millionaires and billionaires; cut the rules for Wall Street and the special interests; and cut the middle class loose to fend for itself," President Obama said. "That's not a prescription for a better future. It's an echo of a disastrous decade we can't afford to relive." President Obama said Republican proposals showed they were the ones not listening to voters' desires. "And for all their talk about reining in spending and getting our deficits under control, they want to borrow another $700 billion, and use it to give tax cuts to millionaires and billionaires," he said.
