I think there is a lot of confusion being sowed on this issue by many people, media, and politicians. The Washington Post recently addressed concerns that Senate Republicans are working to end SS and MC and found this to be untrue.
This is not a news or editorial article, but instead falls in their Fact Checker investigative journalism where the WaPo investigates an issue and assigns a "Pinocchio" scale from 1 to 4 "elongated noses" as to how big a whopper the purported facts are.
For this investigation in September, 2022 they assigned four "Pinocchio" to the claim that Republican Senators (as a group) wish to decimate SS and MC. And note that the WaPo is not generally considered a partisan Conservative publication...I, as a pretty liberal person, use it as one of my primary sources of news.
This article should be available to the public and not behind a "paywall". This gives a good overview of current situation with SS and MC: see https://www.washingtonpost.com/politics/2022/09/27/false-claim-that-senate-republicans-plan-end-soci...
Of course, SS (and likely MC as well) has definite funding issues. The SSA itself has been broadcasting this for years that benefits will be cut, by law, once the SS trust fund is depleted in a dozen or so years...unless changes are made to current law. This topic has been discussed in many threads in this Social Security forum, you may wish to read through some of these. The threads often contain a lot of misunderstandings, etc, but there are some posters who have a great deal of understanding of the issues involved: current laws, ramifications of current laws as we approach that date of 12 years from now, and what ideas are in play to put things on a firmer basis. In some ways this is like the situation of 40 years ago when under President Reagan's terms the rules for SS were put on a firmer ground. Now we're at the point where this needs to be done again.
