“A good beginning is always important in order to form a virtuous circle. I am the only one who currently needs to buy the gears, so I have to provide the tools while they provide the manpower. They will also get paid. In the future when there are others who have a demand for gears, they will realize that having their own tools will be better than renting the machine and earning the remuneration provided.” When Roland spoke up to here, he paused for a moment and then said, “In this way, when they see something new, they can first rent the machine and decide later if the market is big enough for buying their own machine, and if not they will just continue renting the machine. This is a virtuous circle.”
