You have asserted an opinion without foundation.
I wrote an article on SS Medicare and Obamacare that has a lot of info on your question.
A Ponzi scheme (/ˈpɒn.zi/; also a Ponzi game) is a fraudulent investment operation where the operator generates returns for older investors through revenue paid by new investors, rather than from legitimate business activities or profit of financial trading.
The government requires new workers paying FICA. They did this in the 80s by adding government workers, Congress and other members of the public sector. These workers didn't need SS or Medicare they had FERS and FEHS. The SS and Medicare is just a fringe benefit.
The point is that the SS and Medicare Trust funds have been inadequate to pay benefits of an aging workforce. Medicare has been infected with numerous and continual major fraud.
Operators of Ponzi schemes can be either individuals or corporations, and grab the attention of new investors by offering short-term returns that are either abnormally high or unusually consistent.
In the case of government they just make it a mandatory law, and before it is really a tax, they have SCOTUS backing because TAXation is found directly in the constitution.
Companies that engage in Ponzi schemes focus all of their energy into attracting new clients to make investments. Ponzi schemes rely on a constant flow of new investments to continue to provide returns to older investors. When this flow runs out, the scheme falls apart.
This need for new workers is the reason that FICA is a Ponzi scheme.
Without the new workers the Trust Funds go dry.
That is why the government has modified the SS and Medicare.
SS by raising the retirement age to slow down the drain on the fund.
Medicare by using the donut hole, and requiring medicare users to pay for health insurance. They even take it right out of their SS benefits.
Brad says --- how fair is SS compared to what the people give to the public sector employees and congress.
SS and Medicare require mandatory payment into FICA as long and forever that you are a wage earner.
Workers entering the workforce today most likely will die or wait more than 50 yrs to get benefits. This is the ponzi part.
SS benefits are added to your AGI on Income TAX if you have additional income besides SS.
There is no vesting of SS retirement benefits, and no def of benefits.
