I am not a smart man

Math was never my strong suit, but I have a question for my local readers. With property taxes spinning out of control due to the new reassessment measures (30-100% higher in every county) why are local governments strapped for cash and looking for other ways to raise funds? Indy has seen property taxes double and more, but still raised the local income tax by 60%. I do not get it. Please help me understand.
