I would note that even with pay adjustments, civil service employees as a whole remain behind their private sector equivalents in pay and benefits, particularly those on the General Schedule or Wage Schedule.

GS 5 & 7 will never be lucrative and even at GS-15 Step 10, a person would still be way behind their private sector counterpart.

Clearly Federal pay is not excessive, except in the EXTREMELY rare cases of individuals like Fauci, who are in those positions, which you could count with your fingers, that are not covered under the regular civil service rules.
