Governor Pritzker of Illinois has been pushing a ballot measure that would change the state from a flat-rate income tax to a graduated one. The Governor, heir to the Hyatt Hotel fortune, has contributed an eye-opening $56.5 million to the Yes campaign. Not to be outdone, Ken Griffin, founder of Chicago-based Citadel hedge fund, has contributed $46.75 million to the No campaign. Today’s form of political equality.
