To view it from a slightly different perspective, just look to Japan and their current problems with an increasingly disinterested/romantically-jaded population -- their entire culture is based around their work ethic, and now their population rates are dropping: http://theweek.com/article/index/254923/everything-you-need-...
It'll be a long time before we get to the basic-income/work-optional utopia that will probably be needed to fulfill the entirety of the world's population, and Japan-style workaholism/social issues already seem to be around the corner, so it's really about going with what's the most practical and/or quickest to implement in the meantime.
Everyone has the own idea where the line should be drawn but I think you can be professional and still find someone.
