Workers pay into the system through payroll taxes.
Then those workers get payments after disability or retirement or, to family, after death.
(In practice, it’s not this smooth due to payroll taxes collectively not being a constant.)
So far nothing has been accurate, so I’d at least like to see your work so I can understand your perspective.
Social security death benefits have a family maximum.
As a widow with six kids, we don’t get payments for seven people. We get payments for 2-3 people split among seven.
