I agree, the company in total loses value when it shuts down, the employees are left without any jobs causing loss of livelihood , investors are left with a loss in share value.

Employees can get another job , investors can diversify and manage their portfolio better, there usually higher risk inherent when higher growth and dividends are expected.

What I am saying is everyone is affected when a business shuts down, its not something which affects only investors, employees are also affected, but when the company has record profits in most cases it is provided exclusively to investors and no portion on the profits are shared with employees. I see salary as a way of booking the employees time, a share in profits is what they should get for how productive they are in the booked time.
