We’ll pause here while defenders of an ever-larger public sector dredge up stories of this or that company that didn’t do a good job for an Illinois government. But rising public opposition to property taxes, plus the enormous budget pressures driven by unfunded pensions, sooner or later will force Illinois governments to change how they do business. Think of all the backshop operations — payroll, benefits administration, purchasing — that private-sector contractors just might handle better, and for less money. At minimum, Chicago’s City Hall won’t incur pension expenses for Gallagher Bassett employees. That alone is a break for city taxpayers.
