Do you find government agencies to be inefficient?

Why are government agencies allowed to be run and operated so inefficiently?

I’m talking about the DMV, the Social Security Office, the Unemployment Office, and the like. If you must interact with one of these agencies you’d better take the day off and prepare to stand in very long lines to have very inefficient conversations and hopefully get some sort of resolution.

If it were a privately owned and run operation then there is no way it could operate in such poor manner. Why is the government allowed to run a shitty operation because we are all forced to deal with them?
