If Congress is going to cut Social Security and Medicare, they will also need to do more to encourage employers to hire back workers that get aged out of companies.
Age discrimination continues to be a problem.
Social Security was adopted into law in 1935. At that time, the average life expectancy in the US was 60.7 years. That number peaked at nearly 79 in 2020 (thanks to COVID - and vaccines), it's dipped to about 77 now, but the problem is clearly that the SS retirement age has barely moved while the baby-boomer population funding this scheme is almost entirely retired.
The benefits age should have been decreed to move along with life expectancies over the past 9 decades. The public wouldn't tolerate bumping it all the way to 82 or 82 in one shot today, but slowly incrementing the number toward the mid-70's while decreasing the benefits for those entering the system (essentially mandating 401K-style savings) may be the only way to save the system.
