Abundance is relative and exists on a spectrum. Having more of some resource than you need for the day implies abundance for the day, but if you don't have enough for tomorrow as well then it's relatively little abundance.

If we take abundance in this context to mean enough resources for the average person for the foreseeable future then we have wealth as a species that we've never had before. I believe we have something akin to Parkinson's Law governing human behavior: the demand for resources grows until it consumes the available supply. Gluttony and greed have been with humanity for as long as we've been around and will continue. Not placing any moral judgments on that by the way. That's just an observation.
