n4807g, it's interesting data, but I'd need to dive into the details.
I went to the BLS website, and it's very data rich, so I expect it will take me an entire afternoon to understand the data.
In the mean time, I have a few open questions. Such as, do the private sector rates include minimum wage jobs such as the fast food industry, retail store clerks, and other low pay jobs? I would assume so. But how would you compare an industry pay scale with those jobs in the average, compared to government work, which predominately includes teachers, police officers, and other higher wage jobs - and I might add, with high expectations for quality of service?
I get your point that government work should be benchmarked and adjusted against a private industry baseline, but I would go further and say that it should be to equivalent job classifications, too. Government workers are human beings with skill sets (and often college degrees), so it doesn't make sense to treat them against a number from the private industry that has lower wage, unexperienced jobs in the average.
