not sure but im not one of them, i live in hud housing and we're not allowed our own business which couldve helped me out a lot cause of being out of work
We're all involved in business somehow. Even if you buy something for a penny, you've done "business". It's just a term used for someone who owns a business, or given to someone who makes a LOT of business for someone else.
I accidentally became a landlord when my daughter moved out of the house we were trying to help her buy. I sell accommodation in exchange for rent. I guess you could say I'm in business in a small way. It was purely accidental.
