Slight difference.
The purpose of business is to make money for "somebody". I would hazard that that somebody is the owner of the business. Anything else, including customer satisfaction and "people who do the work" is secondary.
When owner of the business is actually not a single person but stockholders, things get more complex and fuzzy, but the main principle holds: the purpose of business is to earn money for its owner.
Now, I may not like thi sistuation, but it is what it is, given human nature. Any other "purpose" that was tried quickly degraded into either same thing with different owners (Soviet Union) or business disentagration (no more money is made)(Amtrack).
