This is too vague. They're to make the owner(s) money by voluntary exchange of value with customers. They're not feudalism where the lord makes money off the serfs, who have no choice. It's not monarchy where..it's basically the same. It's not socialism, where the bureaucracy is enriched by the people it pretends to be a fair parent-surrogate to. It's just free interchange of value. And you can provide more value if your costs are lower.
