It is interesting to examine certain programs started under the New Deal and realize that some of the feelings that the politicos of the time had about them have been realized.
One program about which conservatives were skeptical is the Social Security system which began in 1935 with the Economic Security Act of 1935. Taxes for this act were begun in 1937, and until 1983 it was a pay-as-you-go program.
The 2014 Social Security Trustees report showed a continuation of the current trend toward insolvency of both of its trust funds. As in the previous two years, the Trustees estimate that Social Security's combined retirement and disability trust funds will become exhausted in 2033, less than 20 years from now.
Another program that conservatives disapproved of was the Tennessee Valley Authority which they felt was socialistic in design. The TVA certainly has been a successful venture and has provided electrical power to many places that hitherto had had none. Moreover, it controls the Tennessee River flood waters and has improved navigation. So, in hindsight this was a program that produced jobs for many and has proved profitable. Still conservatives may have pointed to it as the beginning of government control over what should be left to private enterprise.
Progressives were glad that FDR pledged to re-create the war social programs of the Wilson administration, a goal that was wildly popular at the time.
“I want to assure you,” Roosevelt's aide Harry Hopkins told an audience of New Deal activists in New York, “that we are not afraid of exploring anything within the law, and we have a lawyer who will declare anything you want to do legal.”
Some of them even called for FDR to become a benevolent "dictator," and do even more.
