FLE - In this Aug. 14, 1935, file photo President Franklin Roosevelt signs the Social Security Bill in Washington. For millions of retired and disabled workers today Social Security is pretty much all they have to live on, even though monthly benefits are barely enough to keep them out of poverty. Monthly payments average $1,237 for retired workers and $1,111 for disabled workers. Most older Americans rely on Social Security for a majority of their income; many rely on it for 90 percent or more, according to the Social Security Administration. (AP Photo, File)
