You are absolutely right! And growing up with parents who were children during the war with even less. My dad still saves bits of string and old wrapping paper even though he could afford to buy every ball of string in the shop. I'm always amazed when I read "credit crunch" tips like take your own packed lunch to work!!!!!
On the subject of being "poor", my dad, a wonderful 85 year old, has no truck with modern idea of poverty. He says being poor is when boys stood around you in the playground watching you eat an apple and asking you if they have your core to eat.
I like to think I've instilled some ideas of money management into my children, but was shocked to hear that eldest son in London, good job, takes 5 work shirts to the dry cleaners every week to be laundered and ironed, can't believe I brought up someone who can waste money like that!!!! However, everyone is different ( another of my mantras)
