You must not have read basic literature about FEHB. Here is a link about post retirement benefits. The taxpayer subsidizes most of the premiums. This benefit is especially important for the large number of federal employees electing early retirement before Medicare.

Since I worked for my income, and all of it came out of non-tax revenues, your insults simply don't have the power you want them to have. My retirement is also an EARNED BENEFIT and my former agency actually paid for it and for my current medical insurance.
What you need to do is GET EDUMACATED and learn how the federal government really works.
