Why does my boss put his friends as "officers" and "admins" on the company's facebook group..?

[what goes around comes around]

..instead of the actual people who work in the company??
My boss has created this facebook group for his company. But I noticed that admins and officers on this group are only his friends or relatives. He never puts his own employees who do the actual work as admins or officers. I know it's a silly question, but I'm just wondering why coz me and other coworkers actually work for him and he never considered assigning us as officers.
My boss is actually young like 28 years old and he uses facebook all the time and he even added me as a friend but why does he do that I wonder? He likes my work and everything but why doesn't he show that to his clients on his facebook group??
