All higher species on Earth are prone to addiction as far as I can tell. Arguably, addiction is a biological necessity. There aren't many situations where seeking more of a good thing isn't evolutionarily successful. There can be particular niches that go against this principle and they may even be the ones eventually surviving a "consumerist" selection event but from an evolutionary point of view I would expect a civilization to evolve from a consumerist species. I also reject the hive-mind hypothesis. This could be more of a terminology issue but, as I understand the term, in a hive-mind, every single mind is less important to the collective and overall survival is easier leading to a weaker evolutionary drive towards higher intelligence. A highly interconnected individual-based civilization seems more likely to me. It has all of the upsides and none of the downsides when compared to the true hive mind.
