What transferable skills do drug dealers have which are transferable in the business world?

I read about this a few years ago, don't remember the author unfortunatley, but it was a properly funded univesity study into the business practice of drug dealers and it turns out that the whole business structure of drug dealers is almost exactly the same as McDonald's business structure - seriously - not that McDonald's sell drugs, but in the organisational and business structures they can be seen to be very similar. Do a bit of digging on google for this - you will be surprised.
