Businesses are for-profit organizations that exist on the local, regional, national and international level (maybe interstellar...) domain of the Major Deej Universe (MDU). Businesses provide services, equipment, manufacturing and associated processes for design, development and delivery. Some businesses can be fronts for criminal activities, however, a majority of businesses in the MDU are benevolent and are deemed capable of profits if their practices follow existing  legal systems in place in their location.
 

That's not to say their aren't 'illegal' or 'immoral' businesses in the MDU...they exist too!
