You said significantly, the difference is marginal between educated workers even in this data set, and as I stated this data is biased by inclusion of the admitted higher fed pay before 2010 when federal wage and hiring freezes began. There is no data more current, but anecdotally contractor pay is now higher in the RDT&E domain.
I didn't say that, at all.
What I said was: "federal government workers earn substantially more in salary and benefits than those with equivalent jobs in the private sector". You have provided NO data that refutes that.
