I don't get what you folk are grappling with here. It's a simple example of successful innovation..
It was designed for high-country shepherds to speed up the hike up to the top hut, plus you could carry a few more tinnies than you could fit on your horse.
Then you drive the sheep down to the woolshed to be fleeced.
Then somebody had a great idea.. maybe the same machine could be used to fleece speculators! )
