Billionaire financier Ken Griffin committed $20 million campaigning for Illinois not to raise wealthy residents' taxes

• Ken Griffin is campaigning to prevent his home state of Illinois from implementing a progressive income tax system that would charge the wealthy more.
• Griffin, the billionaire hedge-fund manager behind Citadel, donated $20 million to an organization advocating against the tax changes and wrote an op-ed in The Chicago Tribune about the proposal.
• Other states facing budget shortfalls, like New York, have even debated implementing specialized taxes on billionaires' fortunes to avoid further cuts to education and health care budgets.

From how he's been writing and donating, Ken Griffin really doesn't want Illinois to change its tax scheme which would raise the taxes of wealthy people like him.

The billionaire financier has emerged as a leading voice of the campaign against a proposed change to the state's income tax system, donating $20 million to an organization advocating against the tax changes and writing an op-ed in The Chicago Tribune about why he's opposed to the proposal.

Illinois is one of the last states in the country with a flat tax rate where everyone pays 4.95% of their income, as 32 states and the District of Columbia already use a progressive model in which the wealthiest residents pay a larger share of their income.

While proponents of the change, including Governor J. B. Pritzker, say the proposed new structure will be fairer to the states' neediest residents, Griffin said in a statement to Business Insider that it will lead to higher taxes for everyone in the future and send other residents packing.

Griffin, who leads Chicago-based investment firm Citadel and has an estimated net worth of $15 billion, is known for his sprawling real-estate portfolio estimated to be worth $1 billion on its own.

Griffin isn't the only member of the state's three comma club getting involved in the tax debate. Equity Group Investments' Sam Zell donated $100,000 through a real-estate trust towards efforts to subvert the tax. Pritzker, a billionaire of the Hyatt hotels dynasty, gave $56 million of his fortune to a pro-tax campaign, per CNBC.

Illinois has been in a fiscal crisis for years, and it was only worsened by the coronavirus pandemic. Other states facing shortfalls, like New York, have even debated implementing specialized taxes on billionaires' fortunes to avoid further cuts to education and health care budgets.

Read Griffin's statement in full below:

"People aren't waiting until November to vote against the economic hardship created by the Springfield's spending addiction — they've been voting with their feet for the past decade as Illinois has lost more residents than any other state in the nation. In that time, two tax increases have already failed to improve our situation, and what's now being marketed to voters under the guise of a 'fair tax' is nothing more than a graduated tax scheme engineered to extract the greatest amount of money possible from all Illinois taxpayers. As we've seen in other states with a graduated tax scheme, everyone inevitably pays a higher rate. It's time the Governor and Illinois legislature stop taking advantage of constituents and wasting hard-earned taxpayer dollars. It's time for the governor and the legislature to focus on spending our money wisely to provide for better schools, better public safely, better infrastructure and greater opportunities for all our citizens."
