I would, someday, like to start a cooperative of some kind. I think that software would be an excellent place to start. Software companies tend to be high margin and have low start-up costs. Also, the most substantial ongoing cost is labor. So, if everyone is an owner and not paid a salary, we no longer have to spend as much time allocating resources.
There are two big problems. One: I don't have an idea. Two: I don't like doing things for money. Whenever there is the need to turn something profitable - I become disinterested.
I'll solve problem one first - maybe I can overcome two at some later date.
