Americans say they have weathered the worst of the longest recession in seven decades, even as they are pessimistic about prospects for their retirement years, according to a Bloomberg National Poll. Three in five respondents to the Oct. 7-10 poll say their economic condition has improved recently or they are confident it will get better. One in three say things have gotten worse or aren’t likely to improve anytime soon. “I see some hope, but not a lot,” says poll respondent Brian Ridlon, 34, an out-of-work resident of Green Mountain, Arkansas, who wants to learn how to become a barber. “There are some avenues to improve yourself, but we need more.”
