Lost words of wisdom.

Browsing around the net I can across this collection of WW2 posters. They're great , simple effective . It makes you wonder why we seem to need a do or die situation to do the right thing. In them days words like conservation , being frugal, saving were considered a virtue while today these are considered anathema! Media tells us to "buy", "shop till you drop" ,"travel more" , "what you had yesterday is not enough today".
Do we need WW3 to start doing the right thing again?
