As this article on USA Today.com explains, Federal employees earn higher wages  than comparable workers in the private sector in more than eight out  of 10 occupations. I have included a section of their article below,  but you can checkout the full text – including a comparison chart  – at USA  Today.com.
 
Accountants, nurses, chemists, surveyors,  cooks, clerks and janitors are among the wide range of jobs that get  paid more on average in the federal government than in the private sector.
 
Overall, federal workers earned an average  salary of $67,691 in 2008 for occupations that exist both in government  and the private sector, according to Bureau of Labor Statistics data.  The average pay for the same mix of jobs in the private sector was $60,046  in 2008, the most recent data available.
These salary figures do not include the  value of health, pension and other benefits, which averaged $40,785  per federal employee in 2008 vs. $9,882 per private worker, according  to the Bureau of Economic Analysis.
