Why collaborative consumption now?

Is collaborative consumption because of our financial constraints since the 2008 financial crisis or is it something we do even when we have the financial resources?

I believe the collaborative consumption trend stems from a few movements:

• movement away from materialism because of moral conscience:  Knowing that the most coveted iPhone or Nike sneakers is made in less than ideal circumstances makes owning a lot of "nice" things for the sake of showing off less of a status symbol and more of a blight on your reputation
• seeing how overwhelming it is for our parents to down-size and and discard their many belongings, and thus a striving for minimalism (http://www.theminimalists.com/)
• environmental awareness - in general, less consumption means less stress on the planet
• an awareness of mass production and duplication and therefore (1) a desire for uniqueness and personalization by hanging onto certain things (e.g. furniture, clothes) and making them "your own" by customizing or skinning and/or (2) it is undesirable to accumulate mass-produced copies
• desire for physical mobility and exploring the world - owning stuff ties you down
