Also keep in mind that when SS started it had six people paying into the system while one was paid out. Today that ratio is almost 1:1.
Longer lifespans, altering the original intentions of the program (like the IRS code), plus the disintegration of the family resulting in the lack of children being created is bringing about its bankruptcy.
Good info on the SS system from 1964.

Self-Supporting
“The program is designed so that contributions plus interest on the investments of the social security trust funds will be sufficient to meet all of the costs of benefits and administration, now and into the indefinite future—without any subsidy from the general funds of the Government. Both the Congress and the Executive Branch, regardless of political party in power, have scrupulously provided in advance for full financing of all liberalizations in the program.”
Where your money goes! Read and weep!
