You were probably downvoted for taking the position that you are the judge of what other people need, but besides that error, I think you bring up an interesting point.

It is an uncomfortable truth that we have yet to really contemplate as a society.

Consumerism ISN'T sustainable, and society will grow to a point where we are going to see seemingly fundamental systems start to crumble beneath the sheer weight of consumption.

We have to be willing to ask "should we?" in addition to "can we?"
