Over 30 years of retirement, Chang would collect as much as $3.36 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Chang received $70,604 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Chang will have already received $295,381 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
