Oh, such a great post Kristen. I am looking forward on catching up on what your readers think on this topic. 

For me, I know I cant solve the issue, I know many do not see this as an issue. I decided many years ago to let go of what 'they do/want' and chose to live by the addage 'less IS more'. I too was/am discusted by excess - in more areas than just square footage or price. I do this first by appreciating my small home (990sqft) for its location and large yard space. When it feels a bit too small, I think of my fmaily in Holland who thrive in even less space. I do not see moving up to a newer, 'better' neighbourhood as a measure of my success. 

Before I ramble on, I would like to say it isn't the cost of the real estate that disgusts me so, but the ideology saying that it's desirable.... I do look at celebrity excess with disgust though, often thinking if only they would live 'reasonably' - what could be done with all that money...  

Parlaying those thoughts into what I model for my kids can be summed up with a recent comment back from my daughter when we were discussing a fee for a camp - she responded with 'experiences over things, right Mom?' - though self serving, I could not have been more proud of her. Plus, grateful my message was making it's way through.
