That's not what he's comparing himself to, he's not comparing himself to people with sick parents, disabilities or a family to take care of. He's comparing himself to young and educated indulging the life of well-earning bachelors buying shit they don't need.

If one has started a family and doesn't have one's own successful business yet, it's very likely to be forever stuck in the "job-limbo", because one does have responsibilities. Family is the most important thing.

Speaking for myself, I just couldn't start a family without having my own successful startup before, because otherwise I could never give myself and my children the freedom that I consider to be necessary to make a life worth living.
