Is this a reasonable statement to make do you think?
I don't think it is because I think that on the whole society generally measures "success" in terms of what people achieve in terms of tangible or material things and that inevitable involved making comparisons with others.
To illustrate, you can say all day long that Richard Branson is no better than you are (and he probably isn't) but society will always view him as more successful simply because he has more money than you do.
