11. Agriculture Businesses A country can survive without some of the top businesses on this list, but it will not survive without agriculture. Agriculture is a country’s source of food and since everyone eats at least a meal a day, agriculture is a business with a ready market regardless of where you are. Even though most millionaires and billionaires who make their money from agriculture invest in large-scale production, they all had to start somewhere. Agriculture has a ready market and everyone interested in it can make millions, especially with the use of modern tools, equipment, and methods. Some of the leading agriculture businesses in the world include Bernard Matthews Farms, BASF, and AVEBE.
