Think of the tough times that goes into a business like that and all business.
Say they produce 3000 babies but do not sell alot of them right away. That is alot of babies to keep feeding,cleaning, watering not only for the supplies but the manpower to do so. I am sure that insurance, loans, employee pay, taxes, utilities, not to mention having to stay on the cutting edge of the B.P. market to stay ahead of the small/medium size breeders take a pretty nice chunk out of the total also.
Not saying they do bad but I help run a construction businees that does around 10 million a year in business. You better believe that I do not see anywhere near that amount of money and would bet that alot of people that do not own a business make more than I do with half the stress.
