The recession appears to be ending, according to a report issued Wednesday by Federal Reserve Chairman Alan Greenspan. Iowa Senator Tom Harkin says he hopes Greenspan is right.While Greenspan said the “recuperative powers of the U-S economy…have been remarkable,” Harkin says the key will be growth in the coming months, and without it, the economy may lapse back into a trouble zone. Harkin says he’s concerned that future budget deficits will keep long-term interests rates high and create slow growth in the economy.Harkin says he “can’t believe in one year we’ve gone from the good work that was done over the last eight years in getting out of the deficit hole…and now we’re right back where Ronald Reagan put us in 1981.”
