I wouldn't say money addiction, I would say quest to live a comfortable life. We have to work continuously non stop to earn a living if not we will starve and won't be able to provide our necessary needs as humans. Commodities keep increasing in price everyday so therefore we have to double the hustle to be able to purchase them. And one needs more money because more problems keep piling up.
   An average married man with 6 kids will have to double his work in order to be able to fend for his home.
