It is very true JP - the Global Footprint Network calculated that in 2008 we used 1.4 times the Earth’s annual sustainable resources...so we just can't carry on like this! The issues lie though in changing the social acceptability of what is almost a "disposable society". It's complex stuff, which believe it or has evolved in part from the need for sexual equality and the acceptability now of women as well as men going out to work, and increased divorce rates etc. I did a very small piece of work on this in the summer as part of my uni work - but only really scratched the surface.
