This seems a rather dangerous view, as the post scarcity era of maybe the late 20th century globalism, or the larger industrial revolution and coincident population explosion, could be nearing it's end. Peak cheap oil may be just around the corner. The growth built atop improving agriculture yields, cheap oil, and cheap labor has resulted in population growth that cannot be maintained without corresponding sources of the same cheap input sources.

And part of this is exacerbated by what you describe: a huge portion of population not subsisting on their own work output but depending (or being subsidized by) the work and resources of others.
