5 idiots are in a business that is commission based. There are only 5 operators in the industry. Business has been bad because the main operator of the business has turned it into a gambling den instead of the real business it used to be, when genuine goods were exchanged. Now the business is all about toxic notes that were printed from thin air.
The 5 idiots could not figure out why the business is running out of steam. In desperation, given the 5 IQ they had, one is suggesting to cut commission to gain market share. This idiot could not see one centimetre ahead of him and could not think that if he lowers his commission, the other 4 idiots will also do so.
So when one idiot comes out with his brilliant plan, the next will follow with a betterer plan. They will keep the cycle of commission reduction going on and on, from 5c to 4c to 1c, to 0.1c and so on and on, as long as they think they can gain market share.
And they are congratulating themselves for being so idiotically brilliant.
