And that is what economics is, competition. Some win and some lose.
Longevity can be the luck of the draw or life choices. But, some people don't have good choices, so maybe everything is hanging by luck.
Some people are uncompromising some are easy. Some people sell themselves into bondage of sex, drugs, upmanship, money etc.
There is one equalizer, no one get out of here alive.
