Overseeing a dispirited nation, US President Barack Obama on Saturday sought to assure people that bleak times will give way to better days, calling the mounting economic crisis a time to discover America's next "great opportunity." "That is what we can do and must do today. And I am absolutely confident that is what we will do," Obama said in his weekly radio and video address, taped on Friday at the White House. The work week ended on another dour note, with 651,000 more American jobs slashed in February and an unemployment rate climbing to 8.1 percent. That is the highest rate of people out of work in more than 25 years, as the recession continued to put enormous pressures on families and industries. Obama recapped the work of another hectic week in his young presidency. His goal was to reassure the country that he and his team are taking specific steps to create jobs in the short term and begin to address huge issues, like health care, that affect virtually everyone.
