Are some people inherently naive in thinking that government can solve all society problems and needs ?

I believe that government is inherently inept and inefficient for this reason, no one person or group is held accountable for their actions like in the private sector. If I am a buget director for my company and I draw up a annual buget that goes over by a hundred percent I get demoted or fired. If people in government do it they usually get promoted and they just raise our taxes. I think this is the fundemental reason why government botch up every institution they run ex SS Welfare Medicare, yet their are people clamoring for the government to run the grandaddy of all system health care what is your opinion?
