Private vs Government worker effectiveness arguements generally hold no validity due to the comonly failed 'arguement by selected instance' strategy (a great way to try to prove a point on this BB!).
No matter whether you are in a gov. job or a private job you will find the good the bad and the ugly!
Government jobs are quickly turning into contract positions so if you are not effective, your gone. Not much different than private really.
You can argue that in private enterprise there are a lot of 'jobs for the boys' where working 'benefits' only extend to greedy, corrupt, self-serving individuals and not society, and while the private entreprenuer is working hard at etching a living, they are equally dodging taxes left right and centre, don't have time for their families leaving the rest of society to care for them yada.. yada... yada....You can make an arguement on either side of the fence, depending upon which side your sitting.
For me, no job is necessarily more alturistic/important than another. We all need each other to survive at some level. You can't really define one job as more significant than another (well, maybe you can

). Problem is some jobs seem to attract amazing salaries/income/benefits that may be out of step in a comparison of benefit to society. An example (by selected instance

) might be the soldier vs the private practice doctor/lawyer.
Hmmm...starting to sound very socialist
