Any astronaut looking down from space at night would spot a solid band of bright light wrapped around the southern end of Lake Michigan. The lights go on somewhere north of Milwaukee, stay on as the band moves south through Kenosha and Racine and turn into the glare of Chicago before sweeping east across northern Indiana, finally fading into the blueberry belt of southwestern Michigan.
What our astronaut is seeing is a megalopolis, a super-city, a midcontinental metro -- a region. From orbit, it looks like one big urban area. He can't see any state lines or town lines, which makes sense, because it's hard to see them even from ground level.
But they're there. Oh boy, are they there, and they keep this Chicago region from acting like the one big city it really is. Down here on the ground, it's not one big region but three states, 21 counties, dozens of towns and a couple thousand townships, school districts and other jurisdictions and taxing bodies, all out for themselves, with little regard for the other state, town or jurisdiction next door.
Obviously, this Chicago region is much less than the sum of its parts. This is the conclusion of anyone who's tried to get these many parts to work together and, more immediately, of a major new study by the very authoritative Paris-based economic body, the Organization for Economic Cooperation and Development.
