I thought you might have been mistaken about the 75 years part, so I looked it up. By golly, you're right. And the interesting part is that, going forward, the city must pay the company whenever an existing meter's profits are threatened.
So if the city has to remove a meter, or closed a metered street for repairs, the city must pay the company. I'll bet that's where the real profits will be.
Spending the future estimated income today, as Chicago is doing, is going to be a disaster long term. There will be a day of reckoning in the windy city. I’m sure Rahm hopes to kick the can down the road till he’s out of office.
Daley did the same thing with the Skyway. Look up the details of that deal. It’s mind bogglingly stupid.
