Sorry, my cat walked across my keyboard as I was submitting my response above, and she managed to paste in part of my answer to the question I was addressing. My post above should have read as follows:
Interesting survey. My only question is regarding the one containing the phrase "culture of indispensibility". Are you trying to suggest that our society regards vacuum cleaners as something we cannot live without? Or was the question supposed to address a culture of disposability, in which our society regards vacuum cleaners as throwaway items? I answered it both ways, just in case.
