Based on my personal experience and that of many others I know, that's about as wrong as one can get. A great many government workers are there to collect a paycheck and go home (just like many other people working for many other employers). Their commitment to 'the mission' hovers near zero.
Just ask them.
Where do people get these crazy ideas about government employees? There are some wonderful people in public service, but it's not some Wonkaland of saints who toil just to help others and do the right thing.
