For a student or person struggling, a million sounds wealthy, I suspect. For someone with fair means, it probably sounds "OK". For a person with $10 million, it probably sounds "poorish". There are likely a lot more folks in the first group than the last giving opinions.
We did this poll around here and I think hit on $5 million, or so, as opinion here, I'd guess most of us are doing fairly well.
I think one can retire fairly comfortably with a net worth of $2.5 million IFF one is 65 or so.
