Quote from traderNik:
. You don't have to have a lot of money to live like a man.
Anybody can live like a man, theres 5 billion men out there.
You think its special living like a man?
Lets run this in a MAN's logic format
---------------
Worth = How rare you are
Being a man is not rare , also not of much worth.
having a lot of money = rare = is of much worth.
Pretty simple

You can also be "worth" something if you are the only person with 10 arms, or 7'9 playing nba, or anything that is rare. Easy way to measure worth, most of us don't have 10 arms, so we go for things we can be rare from. Professional Sports/ Trading/Moneyetc.
