A company is a shared endeavor--for those that own shares in it. But for most companies, most people that execute the work are not shareholders; they're just employees. The interests of employees are simply not the same as the interests of shareholders, so any company that has employees will have to deal with that. The larger the company, the more they will have to deal with it.
However if you consider a company as a means to a shared endeavour, then human agency becomes extremely important.
