This is incorrect per the US Supreme Court e.g. Flemming v Nestor in 1960. Social Security contributions are purely an income tax like any other, it is explicitly neither a pension nor insurance plan. Contributions create no obligation for the government to give you anything in return, same as the other income taxes you pay. The government largely treats it as tax revenue.

It is intentionally (mis)represented as a pension plan where contributions are connected to benefits but that fiction is solely to maintain popular political support, they can disqualify citizens from eligibility at any time regardless of contributions and, on occasion, have.

The main issue with Social Security is that most people in prior generations took far more out than they contributed, in part because it wasn’t really a requirement since it wasn’t actually a pension.
