While my incredibly rational side tends to agree with your point, my closer-to-the-reality side tends to think that the real world doesn't exactly operate in a state where "consumerism, environment, politics and income inequality" are not mixed up already.

The picture isn't clear, there isn't a single issue that makes the world as it is today purely by itself. So I would blame consumerism, together with everything else you listed - and I would strongly believe that you need to put the blame on every single one of these things at the same time.
