CHICAGO

I stopped by Chicago’s City Hall last week to interview the mayor, Rahm Emanuel, the former White House chief of staff. I find “Rahmbo’s” Chicago agenda intriguing because it’s a microcosm of what the whole country will have to do for the next decade: find smart ways to invest in education and infrastructure to generate growth while cutting overall spending to balance the budget — all at the same time and with limited new taxes. It’s a progressive agenda on a Tea Party allowance.

Emanuel simply calls his philosophy “cut and invest.” The cuts are coming from long-padded city departments and are going to pay for more cops on the beat, longer school days and modernized subway stations — all designed to create more incentives for companies to create jobs in Chicago. In laying out his new budget last week, Emanuel summed up what it means to be a progressive in this age of austerity.

“I want to be honest about this budget,” the mayor declared. “Almost every one of these ideas has been discussed and debated before. But politics has stood in the way of their adoption. Maybe in the past, we could afford the political path. But we have come to the point where we can’t afford it any longer. The cost of putting political choices ahead of practical solutions has become too expensive. It is destroying Chicago’s finances and threatening the city’s future. In all of these reforms, we will be guided by principle, pragmatism and progress — not politics. What we simply cannot do is to temporize any longer. We can’t kick the can down the road because we’ve run out of road.”

Indeed, we have. Emanuel’s pride and joy is the new mandate that he and his schools chief, Jean-Claude Brizard, pushed through for next year to have the school day for Chicago’s 400,000 students extended by 90 minutes and the school year by about a week. The teachers’ union leadership has accepted that this will happen but wants more say on how to use the time — and more money. Parents are thrilled, but it will clearly require more talks with the union.
