This message comes from Muji.com. I don't know whether Muji has been reading The Underachievers Manifesto or Bill McKibben, but they certainly are saying something that is out of character for a retailer. Page down on the Muji site and you'll see the rest of the message.
This is a different idea about "growth." Finding satisfaction in restraint and compromise instead of "more" is straight out of McKibben's book Deep Economy. If Muji really is taking a stance against consumerism (and it does seem consistent with their no label brand, but hard to believe coming from a retailer) this makes them a very early adopter of this new vision toward a sustainable economy and very unique in the market.
