Plus anyone in a physically demanding job just don't see how it makes sense.

There are plenty of non-demanding jobs. I had a desk job. Could probably do it as well now, at 72, as I did when I retired at 58. So, the old phartz take all the desk jobs. The younger generations do the hard work, until they can't, then they are cycled through desk jobs.

I remember some luminary on bubblevision, years ago, offering that "in a perfect world, you would die the day you receive your last paycheck". Why that day? Your usefulness in making rich people richer ends. I remember Bush 43 singing the praises of some farmer, supposedly in his 90s, who still got up at dawn to work his farm. The local news here was fawning over some guy in his 90s, who still works as a car salesman for a local dealership. The narrative has been bubbling for years now, that people should work as long as they are able. I have seen a vector of that argument offered to people complaining about rising prices: "work more hours".

That is what informs "Plan Steve", when I put my MBA hat on: for able bodied people, regardless of age: work requirement for Medicare benefits, and no SS old age pension. Let's promote "Plan Steve" with a narrative that "100% of people who retire die, while a much lower percent of people who work die, so forcing people to keep working is good for them, because they will live longer".
