Yes the actual work that is getting done by the company or government is important too. Private companies generally do better at efficiency of getting work done (products or services being produced) than government. This is because government agencies are burdened with an unimaginable amount of levels of bureaucracy which kills the shit out of any efficiency. The government is the ultimate bureaucracy.

Anyone who has worked for both the government and private sector can tell you all about this. When I worked for the government it was the most boring job ever and there was so little actual work getting done that I would sit around reading a book on the job, waiting for something to do. At every non-govt job I've had that would not fly because the employer would see the dollars vanishing for my paid-to-do-nothing hours and put me to work doing something productive.
