Indeed, when 'equal' partners negotiate a division of the value generated by the enterprise or 'company', that's probably about as fair as you can get. That would be called a 'co-operative' I think.

But that's not remotely the same as a company owned by a single individual, hiring employees who 'negotiate' their salaries in competition with other people who need employment - especially considering countries with very low wages, no social security (ie get a job, whatever the pay, or starve), etc.
