Federal Judges

It seems quite sensible that Congress sets the pay for federal judges, however I do not agree with the fact that their income remains the same even after they retire. A federal judge may retire at age 70 if he or she has served for at least ten years. At the time of this retirement it is stated that they will continue to receive full salary for the rest of their lives. The same goes for a 65 year-old judge if they have served for at least fifteen years. I am all for giving hard-working federal judges benefits after they retire but I do not feel as though our government's money is being spent in the most wise way possible if we have to not only pay those federal judges in office full salary, but also those who have retired. I think there are plenty of other systems that could be worked out, that these judges would agree to, that would reward them for all their hard work without spending money so frivolously. This seems especially absurd that continue to receive full salary if they are on 65 years old because for most, they still have quite a bit of life left.
