I don't have 36 minutes to watch that. My two cents without seeing the documentary is it depends on the means and the ends of the business. If the means involve sweatshops in China to produce an ends of a pair of Nikes, it's hard to argue against it. Conversely, if the means involve developing first aid drones to reach stranded mountain climbers with an ends of... saving a life... I'd argue that's consumerism with a vested interest in the preservation of humanity.
Gross generalizations like the one provided in the documentary are dangerous because they neglect opposing information. Either side of the coin can be argued for, situationally.
I did not watch the video. Just going off the question...
Yes, I believe unrestrained consumerism will threaten humanity.
Which is why I preach producerism and restrained consumption.
However I do believe that we are currently engaged in a slow enlightenment where more and more "sheeple" are becoming AWAKE to the perils of consumerism. This is why we have "off the grid" living and "tiny houses". I won't even go into mass-produced factory farming where animals are treated like hive insects.
Change doesn't happen overnight, it happens very slowly as more CONSUMERS demand different options. Then the money moves in that direction.
For instance, consumers are demanding NON-GMO food so food manufacturers are forced to comply.
For those of you with concerns, changes starts with YOU. Be the change you want to see. Just don't be a limousine activist... I'm taking my private jet to give a lecture on global warming...
