Ralph Martire: Illinois is leaving money on the table with structurally unsound tax policy – Chicago Sun-Times

"Start with the Illinois sales tax, which applies primarily to purchase of goods, not services. That’s a losing proposition, given that the sale of goods accounts for just 17 percent of state gross domestic product, while the sale of services accounts for 74 percent. Failing to levy sales taxes on most of the largest and fastest-growing segment of the economy means the revenue it generates can’t grow with the economy."
