Over 30 years of retirement, Barnett would collect as much as $764,578, according to a projection by Local Government Information Services (LGIS), which publishes Sangamon Sun.
The projection assumes Barnett received $16,070 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Barnett will have already received $49,671 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
