I remember this topic coming up on this forum maybe a year ago. I’ll try searching for it. The question was lifetime earnings to net worth, using SS history for the earnings portion. SS history from the government website was accurate enough for me, though it misses my teen years when I worked part time for cash.
From what I remember of the thread, people with high net worth generally mentioned a lot of housing appreciation. Also, I think they were older and had more time for investments to grow. So, do I think the ratio is useful or meaningful? Not when comparing yourself to others on this forum, but compared to the typical person, maybe.
I just found the concept interesting because I had never put thought into it before. Also how much money I made when I was young, looking at inflation adjusted dollars.
