Oh, I'll give you garbage collection as an example. Years ago when there were metal cans and you had to pick up the cans and dump them into the garbage truck it was a 2-person job. Now we have the plastic 90 gal. cans that have a bar on them an arm on the truck poicks up and dumps into the truck at the pull of a lever. But Chicago, instead of taking advantage of this, still has 3-man garbage crews per truck. A driver, who never gets his fat butt out of the truck, and 2 others who waddle along behind the truck rolling the bins to the truck and pulling the levers. It takes them about 3-4 hours to do their route and they call it a day. For this they make an average of $60,000/year plus benefits.
