> How does [sharing] add value to the economy over the longer term? There is no production. It is entirely consumption. Recycling is all very well – and we do need secondary markets – but we cannot build an economy solely on sweating existing assets. An economy that exists solely on consumption has no long-term future.
Sharing is a process that optimizes usage of available resources. Why should we make more cars than we need? Why should everyone have a boat if not everyone needs a boat? Sure, more boat-building jobs are "created" if we feel everyone really needs their own personal boat, but there seems to be a strong opportunity cost that is being forgotten here: the labor necessary to build boats could instead be directed into a more useful form that advances society as a whole much more quickly.
What do I mean by advance? Well, I guess to some degree that's subjective. But I'm fairly certain everyone can agree on at least some universal goals that humanity would like to achieve, and artificially increasing the number of jobs available for the sake of having more jobs available seems like it would hurt our overall progress in the long run.
I think this quote from Warren Buffet sums up what I'm trying to say much better than I can:
> The way I see it is that my money represents an enormous number of claim checks on society. It is like I have these little pieces of paper that I can turn into consumption. If I wanted to, I could hire 10,000 people to do nothing but paint my picture every day for the rest of my life. And the GNP would go up. But the utility of the product would be zilch, and I would be keeping those 10,000 people from doing AIDS research, or teaching, or nursing. I don't do that though. I don't use very many of those claim checks. There's nothing material I want very much. And I'm going to give virtually all of those claim checks to charity when my wife and I die.
