Well yes - if you are willing to adopt a standard of living from 100 years ago, then you can probably easily afford it with modest savings at age 40 or even less. I'm talking multi-generation homes in a not-very-urban area, maybe a car, and you have to fix a bunch of stuff yourself.
If you wish to retire on the median standard of living from 2024, well, that's gonna cost median wages from 2024. If you want to retire on your standard of living, well, you'll need 40 years of your income to last you till 80. That's hard to do.
The median standard of living nowadays is lightyears ahead of the median standard of living from 100, 200, etc years ago. That's almost all productivity increases spread around to all of us.
