Its is sustainable if you do two things get rid of the recipient (covid vax) and have more pay in that will never get it illegal migrants. See problems solved ut can self fund if no one but government takes money from.it and everyone has to pay into, no one like tax so we call it benefits like healthcare and pension programs. Sound nice but are worse than what was previously there.
Since back in 2001, I have always been under the assumption that SS would not be there for me when I qualified.
Also, due to our falling birth rates (IIRC since 2010), there is simply not enough of those working to support retirees. People began putting off having kids till later in life or not at all. And having fewer of them too. Tack on the “Do it for the Earth! Dont have kids!” climate change ideology too.
What is the solution?
Raise SS taxes, not better.
Raise the qualification age, not better.
Cut benefits, not better.
All three, still, not better.
