 Its 1983 report led to the Social Security Reform Act of 1983.
 Greenspan himself was critical of this act, stating, "Do I like the present Social Security system?
 No.
 If you asked me whether it would be necessary in the ideal society, I'd say no.
 Our type of economy is far removed from where I would like to see it, but you have to be careful about moving from one type of society to another."
