Today we will examine something I refer to as Anthill Economics. The other day when I entered the local anthill, i.e., the bank, the usual staff of 33 employees greeted me. The most customers I've ever seen inside the bank is 10, but that's not the point. The anthill employs as many ants as possible and they are all busy working very hard. What they're actually doing is not so obvious to the casual observer though, even with a magnifying glass.
But after observing the anthill for some years now, I've finally figured out what they're all doing. As in all anthills, there is a hierarchy.
The Security Ants. When you walk into the main branch of my bank, you'll see two security guards standing near the entrance of the anthill by the cash machines. The Security Ants are not armed Macho Ants as you might expect, but elderly Senior Ants who are retired and picking up extra income with this part-time job. They probably acquired their jobs by knowing someone at the bank, since the bank couldn't very well advertise the position: Security guards wanted for main branch of bank. Must be able to watch people take money out of cash machines all day long and if there is a problem, to properly direct them to the teller window.
