I live on about 30% of my net income (and about 18% of gross), not including trading and other activities which I do not count.

Not bad.

Many Americans either by poverty or lack of financial discipline and status competition live on 130% of theirs.

Money in our society alas is power, and freedom. I value that more than having a really nice house or even extremely expensive cars.

Don’t care about status competitions or the like, either. Screw the lawn. I won’t work until I drop dead, how’s that? That’s my status update.
