Interesting discussion. I have not read all the posts, but I can assure you it is not only America going through this. It is happening in our country (South Africa) as well IMO.
Especially under the richer income class. I have seen the oposite in lower income classes.

This is my opinion outside of USA and how USA is portraid through telivision: who you are is difined by what you own in luxury items. If you don't own the newest gadget,clothing, latest hollywood trend as advertised you are lame and not worthy to a certain extent.
