System. “(businessdirectory.com)
In a closed system business exist when the only money exchanged is within the domestic circle. No domestic business or products come into play, money stays within the system. There are no leaks of foreign players in this system.
An example of this would be a consumer at a farmers market. They have money earned that they want to use to purchase a product that is produced on the local farm. The local farm has land here in the United States and he purchases his seeds and fertilizer from American companies. The funds all stay here no foreign or domestic trades are involved in the production of the product. Another example would be a flag company here in the United States that produces state flags. They use local employees, purchase the material from local businesses and have only store fronts in the United States. Again no leaks. But it’s still not a perfect system. It limits growth. You cannot grow without looking at all options. To become a bigger player in the business you will need to explore all options to maintain your product and growth. This might mean looking into different options of labor, product, and location. This can make a closed circle have leaks.
