The best answer is "Roosevelt needed to include protections to the young and healthy workers who were fueling the economic turnaround". Young people at the time were concerned about their well being if something happened to the economy and their jobs. The Social Security Act of 1935 had two parts to it. The first was that it was to help provide support to persons that found themselves unemployed through no fault of their own. The second part was to provide assistance to the elderly and retired workers. These are programs we still have today although not exactly the same as before, most notably that unemployment funds are not attached to Social Security. Social Security provides funds to those who qualify that are retired, or disabled.
