Yes, Lena……I learned this from watching “Shark Tank”.  Some Business owners say they sold millions in product……and still lose money. No profit !  🙃🙂. I own multiple businesses without doing any work…..I own stock in their business, part owner, and share in their profits 😁😎. 
It’s the easiest way to own a business !

The US military complex produces a lot of weapons and makes a huge profit.  The actual loss is the "opportunity cost" for not investing in infrastructure and long term projects which have a direct and lasting benefit.
