re: Capitalism
For starters, it's a meaningless question since the division you set forth is an artificial one.
The socialist myth of "workers" doing everything while the "bosses" just sit around and collect the profits doesn't stand up to even cursory examination. Have you ever started a business? Been self-employed? Worked your way up to a management position? Anything like that?
Most business owners started out creating the product themselves, until the demand required hiring people to help them do it in the quantities required.
