The investment rules governing payroll tax income were also established in the 1935, and are essentially the same ones in use today. Specifically, the 1935 Act stated: "It shall be the duty of the Secretary of the Treasury to invest such portion of the amounts credited to the Account as is not, in his judgment, required to meet current withdrawals. Such investment may be made only in interest-bearing obligations of the United States or in obligations guaranteed as to both principal and interest by the United States." (See Title II, Section 201of the 1935 law)
It goes on to explain that the Trust fund has been in both marketable and special-obligation bonds. And it explains:
Since the assets in the Social Security trust funds consists of Treasury securities, this means that the taxes collected under the Social Security payroll tax are in effect being lent to the federal government to be expended for whatever present purposes the government requires. In this indirect sense, one could say that the Social Security trust funds are being spent for non-Social Security purposes. However, all this really means is that the trust funds hold their assets in the form of Treasury securities.
What changed in the LBJ administration:
This 1968 change grew out of the recommendations of a presidential commission appointed by President Johnson in 1967, and known as the President's Commission on Budget Concepts. The concern of this Commission was not specifically with the Social Security Trust Funds, but rather it was an effort to rationalize what the Commission viewed as a confusing budget presentation. At that time, the federal budget consisted of three separate and inconsistent sets of measures, and often budget debates became bogged-down in arguments over which of the three to use. As an illustration of the problem, the projected fiscal 1968 budget was either in deficit by $2.1 billion, $4.3 billion, or $8.1 billion, depending upon which measure one chose to use. Consequently, the Commission's central recommendation was for a single, unified, measure of the federal budget--a measure in which every function and activity of government was added together to assess the government's fiscal position.
This was all about budgets. The excess Social Security payroll taxes still went into the trust fund. As the article also notes, there were already two other major trust funds (civil service retirement and life insurance for WWI soldiers) when Social Security began. So, this wasn't a new concept.
But, you can skip all that and read the last paragraph:
Finally, just note once again that the financing procedures involving the Social Security program have not changed in any fundamental way since they were established in the original Social Security Act of 1935 and amended in 1939. These changes in federal budgeting rules govern how the Social Security program is accounted for in the federal budget, not how it is financed.
