Over 30 years of retirement, Barker would collect as much as $564,054, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Barker received $11,856 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Barker will have already received $24,068 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
