Yes. Think of it, look around you, what do you see?
I see people shopping even though they really don't need anything. I see people buying 8 of something even though they only needed 2 because it's a better deal to have 8 and by extension it feeds into the 'just in case' fear we so easily give into. I see people getting into more debt by shopping. I see them teaching their children by example that if they desire something that is equivalent to a need so they must buy it now.
What do you see?
This is not all about other people, it is about me, it is about you. None of us are exempt from this. It is to a large degree what our culture is based on. The post war economy was largely based on materialism. Materialism engenders consumerism. Consumerism makes our world go round.
I challenge you to think of 8 things you could easily live without and donate them today.
